I don't know that I'd call it 'apparent'.

My interactions with people in my life are, by and large, very decent. Social media amplifies the bad actors and makes the problematic things seem more widespread than they are, but in fact, it's just an algorithm grabbing the same content you've had your eyeballs on consistently and feeding you more of it. That creates the illusion that the problem you're hearing about is worse than it may be.

I will say, though, that I've become more of a fan of massive retaliation when I do run into people who lack basic politeness. If I'm in the gym and someone's playing music on speakerphone, I will work out near them and turn on the loudest metal track in my playlist at full volume. I keep a stick of gel deodorant in my car to use on the door handles of people who park rudely, and if someone is speaking to another person rudely in my presence I always say something. I try not to answer rudeness for rudeness to a person's face, because just asking "Why would you speak to someone that way?" is usually more effective for defusing people than escalating aggression. (But you get my drift)
