People so affected by peer pressure they would do so much as to convince themselves things which couldn't have anymore of an obvious existence just don't exist and to throw out common sense/courtesy.
Example: I see a lot of "forever alone" people (what many would call incels), and the idea some people such as myself might be asexual is overridden in their minds. Almost in a way that resembles them trying to will it away. Or often the people will cling to terrible judgment habits to sync themselves, in their view, to society.
When someone has a very against-the-grain viewpoint, such as the very infamous one regarding the Earth's shape, even when it's rooted in a certain mindset or point of view that can stand when explained a certain way, it's common to call these people as having a mental condition, either out of mockery or a genuine concern for them. However, by the same token, people don't seem concerned with the issue I just implied, they simply ground it as human nature. To me, either that's a lie or it implies human nature itself is a mental condition, perhaps the mental condition, and I'm glad if I can say I'm not a part of that, either despite or in spite of being neurodivergent.
