I've definitely turned into the paranoid nutcase within my friend group in recent years, I hate that everything is "smart" nowadays requiring an app/internet connection & account, just to do basic things that didn't require any of that before.
What's some things currently making you ramble like an old man?
The increased normalization of stereotyping. I try to stop myself, but I don't think I'm immune either. It just feels like people are just more okay with seeing that someone is a certain nationality or race and assuming things than they were 5 - 10 years ago, regardless of political orientation. Some communities dislike it when you don't play into the stereotype, even.
I mean the problem is that those things sometimes are not entirely unfounded, though.
For example, I'm absolutely sure that if I would meet someone of Russian nationality, that their chance to think of the "special military operation" as necessary or justified would be statistically-significant higher than in other nationalities.
Of course instead of a 0.5% chance that might just go up to 5%, so not at all "the majority", so starting out to believe any Russian you meet is a war apologist would be absolutely wrong and harmful. However, an increased weariness for the possibility is warranted.
The problem is that the human mind is really bad at correctly assessing such small percentages or possibilities. There is a small difference, and that difference is all that distinguishes two groups, so the group that exhibits that difference is suddenly entirely defined by it, even though that is not true at all.
This happens with a lot of different things and different groups, like you say, and it's important to keep this in mind and work against it, like you say.
