It's absolutely not true that Trump is disliked only for his attitude and behavioral problems (although those are a problem as well, as the president of the United States should be respected and mature and from his tweets you can tell he isn't, but that's not even my main point.
He (and his cabinet) are trying to put in place policies that harm a lot of people. He's trying to limit access to abortions and defunding planned parenthood (what happened to the freedoms that you claim Trump is so supportive of?) which is upsetting because Planned Parenthood helps people not just in cases of abortion but counseling, contraceptives, health care (since a lot of people can't afford to go to expensive doctors) etc.
Also, he's promoting discrimination and policies that will actively harm transgender people. Look at
this article. If policies like this go through (which it looks like it'll be championed for very soon), trans people will have difficulty finding jobs and be allowed to be discriminated against and generally be unable to live their lives peacefully like they want to. All they want is to transition and live happily, a lot of people who are trans are binary (i.e. mtf or ftm) and they live "stealth" which means they pass (look 100% like, you wouldn't be able to guess otherwise, etc) as the opposite sex and get hormone replacement therapy, etc. You wouldn't be able to recognize them in a crowd or individually and they're happy living their lives but they'd be in danger if these policies passed, because of these genetics testing that would reveal them and put them in danger of losing their jobs, losing their place in certain communities, etc. If acts allowing discrimination against them passed, possible employers could easily just say "oh you're trans? HAHA not hired bye" and they'd have NOTHING they'd be able to do. There's already discrimination that goes on under the table, imagine if it was completely legal. They'd have no jobs they'd be able to get in some areas and with LGBTQ people already getting kicked out of their homes and homeless, how would they improve their situation if they're unable to get a job? Die on the street? Fall to prostitution, which isn't legal either?
Also, Trump (as the president) has the power to elect more supreme court judges now that a few of them are looking to be near their time, and if he puts in several supreme court judges that are Republican leaning a lot of previous rulings that promoted freedom like Roe v. Wade are in danger, which puts more women in danger. If a woman really, really isn't in a place to have a child, do you think they'd allow it to go to term just because they have no other legal and safe choice, or would they rather just use unsafe methods they read about on the internet in desperation that people used to do in the past before it was legal? These unsafe methods put these women in danger.
Besides putting in place policies that will literally put all of my trans friends in danger, I also hate a lot of his policies that I read on his 100day list and his choices for cabinet. Public education is so, so, so flippin' important for social mobility so that there's a better chance for poor people to move up in the world (even if chances are already stacked against them due to lack of money) and instead him and his secretary of education (who literally has COUNTLESS incentives to fund private education BECAUSE SHE IS INVESTED IN PRIVATE EDUCATION AND HAS GONE TO PRIVATE ALL HER LIFE AND HAS NEVER STEPPED FOOT INSIDE A PUBLIC SCHOOL NOR SENT HER KIDS TO ONE). Like, school choice is noble and all, but there won't be SPACE for all of the kids in the states and if you're funneling all of your money into school choice vouchers and giving more money to charter schools etc, you're taking away money that SHOULD be going into public schools, which are the schools that the majority of kids have to go to and are already not funded enough, with not enough money for after-school programs, underpaid teachers who have to buy their own supplies for the kids because they care, lack of quality textbooks and materials, etc. How is a low-income kid gonna feel like the USA cares for him and wants him to succeed if his school and textbooks are falling apart as well as his community?
Also, another gripe I have with his 100 day policy, he said something preposterous about MORE COPS in low-income communities instead of funding after-school programs that will allow kids time to work on their homework, allow them time to work hard creatively with art if they so wish, and things that in general would keep them OFF THE STREETS and possibly getting into crime (because peer pressure and idolization of older kids is something that does indeed happen) and then getting in trouble with the law. After-school programs would be so, so beneficial but no, we gotta pay money for more cops. I accept that this is my most shaky point, but nonetheless, I absolutely loathe everything about the Trump administration and have more gripes but don't care to share at 10 AM in the morning on a text forum about animal crossing of all things.
I think freedom is very important, which is why I do not support the majority-republican administration right now.
On the original topic, I personally don't care for it, people should be able to eat in peace, but if a business owner politely says we don't want your business here I support it, I like that they have morals. Freedom in choice in where you take your business is important, but anti-discrimination policies are important, since it's like the gay cake thing, people should not be allowed to not serve cake just because a couple is gay, because what if it's the only bakery in town? If discrimination based on sexual preference was legal, sure they could take their business somewhere else if they could, but sometimes in small towns there aren't a lot of choices so they're just stuck and that would be terrible.
