How are people so detached

As the title says. Personally, I feel like a lot of the people around me have seen too much overly sensitive topics and drama to even consider something, “non-normal” normal to their standards. One case was where a friend of mine was getting pressured into re-dying her hair so it could make her look “more white”, as in race. To me, that was clearly not cool, but there are people on the internet that would just be like “okay, just be more white then” or “sounds like a skill issue” and genuinely believe that it was my friend’s fault for that.

I dunno man, it’s just kinda crazy to me when I see and hear these things.
