What do you mean by preserved? One good thing, in my opinion, that's come of all the political malarkey in the last year is I've noticed forums in general don't babysit people as much as they used to on what they can talk about. It was previously at a point of being so restrictive to where I felt like a child in kindergarten, and genuine civil adults shouldn't have to feel that way... surely?
As I'll always say, this is just my opinion, but I get that the internet is littered with ill intent people, but there's also a lot of civil friendly people too, so a blanket punishment on what topics can be brought up seems very unjust; assuming of course that the place is question isn't having to consider children.
Also, if I understand your other points correctly, I completely agree with you.
