What's something you used to do/see/say but don't anymore because you don't feel it's right?
Me personally? I've become much less tolerant of sexist humor. Back in the day, cracking a joke at women's expense was pretty common when I was a teen. As I've matured and become aware to the horrific extent of toxicity and bigotry pervading all tiers of our individualistic society, I've come to see how exclusionarly and objectifying that sort of 'humor' really is, and I regret it deeply.
I've become less and less tolerant of antisocial behaviour, like littering or being rude to people at the forefront of businesses (bus drivers, cashiers and the like). It's not easy to step up and publicly shame people but I'm getting there.
