I would argue your filter is a huge part of your personality. Many people have harmful impulses, internalized bigotry and think mean thoughts sometimes. Becoming a better person is not about cleansing your thoughts of the impure, it’s much more about keeping your bad impulses in check. Sharing things you would like to keep for yourself, watching a movie with your partner you couldn’t care less about, being kind to someone who makes you feel intense jealousy, these kinds of things. I don’t think it’s fair to say that losing your filter because of a stroke “reveals who you really are”.

I know Fetterman had terrible views before the stroke already. It’s more so that I think it’s scary how you can have a stroke and suddenly become so much worse to the people around you because you lose control over yourself.
