I've noticed the same thing, but I don't think it's something that changed recently. I feel like people with that kind of attitude have always been around and I just notice it more because now that I'm older I interact with more adults (who tend to be more opinionated on politics than teens) than when I was a teenager, and also my politics/worldview has changed, so when I hear someone say something like "I'm not wearing a mask to help slow the spread because I have the freedom to choose not to" I don't think "well that's just a guy exercising his rights because this is America, and that's a beautiful thing" instead I realize "this guy is a selfish piece of shit who would outright kill me to make a few bucks if it were legal, and basically all the people who run shit think that way, and that's fucked up".
