Putting on clothing with collars and buttons is a huge hit to my sense of "authenticity", to start. You feel pressured to to put on airs, deal with smalltalk, etc.
Those who it's fake for are not allowed to throw it off. I get my socialization in groups I choose to be a part of where I don't have to curtail my every thought to avoid political retaliation that affects my livelihood.
And get a PhD before you start throwing around words like "mental issues" for things you disagree with.
