i found an interesting article about the issues of passing and not letting trans people into the right bathroom
http://www.washingtonblade.com/2016/03/23/passing-privilege-debate-conjures-stereotypes/
it's a year old but i think it is very relevant
tldr: picture of two girls (people who look like Girls and all that u know what i mean anyone who looks at the picture will say it is two girls) outside a changing room captioned "so, tell me, which girl shouldn't be allowed in?" one of the girls is trans and the other cis (i assume lol)
the article brings up the issues with this picture and passing (cost, it's often impossible, not everyone wants to) - should trans people really have to look cis to not be discriminated?
i think it is a good perspective. many people mean well when they say things like "she looks like and behaves just like any other girl" when they defend/support/whatever a trans girl. but that's kinda in soem ways counter productive and problematic.
i hope this exppains more about what i meant w/ my last post lol idk it might be unreadable
