Yep. Although…
Is it safe to use the OK hand signal again?
Words and symbols cannot be divorced from context. Like @SineSwiper@discuss.tchncs.de hinted at, putting a date of birth in a username is common and there are so many other meanings for these numbers so it would be ridiculous to jump down someone’s throat for simply using them, or using common gestures. Unless that friend in the story was also saying some reactionary things in their comments, I think it’s silly and careless that someone challenged them on their name.
I been told by some international friends that one of the political flags over in Australia, the Eureka flag, has a similar situation where both trade unions and white nationalists try to claim its legacy, so it’s common to see in both the pro and anti immigration rallies. Context is what makes it either a potential nationalist/racist dogwhistle or a symbol of workers’ rights.

Like some already said, how long ago is “a few years ago”? Because last year my installation had an annoying issue which is now fixed. And maybe five years back, some (newer or rarer) hardware/devices needed a fix through the terminal, but now work perfectly by default.
I haven’t tried Bazzite, but I’ve heard good things about it and what I know about it so far sounds good. Although @jlow mentioned some alternatives which I wonder if they’re even more suitable since you didn’t mention gaming. Out of habit, I still recommend Mint to former Windows users. But I haven’t needed to input a password for web, graphics tools or office apps, only have to type a password when updating, installing new apps or doing special terminal stuff (which I do by choice!)
On one hand, Mint’s default experience (Cinnamon desktop environment) generally resembles Windows which can make the switch smoother. On the other hand, some other ones fix a lot of defaults Windows chose wrong. Even little things, like moving the taskbar to the top (closer to other options) or to the side (takes up less space), so even if you pick a smaller leap to start with, it’s good to casually look around once you’re comfortable.
