...Some things can really go completely over your head if you're not familiar enough with the laws and the culture. I mean when a conversation turns to disability benefits and the like I usually follow, interested, but don't really say anything 'cause I've gotten the impression that that stuff works very differently in America than in here (not that I really know that well about how it works over here, either) so I keep my mouth shut 'cause I really don't know anything anyway. And I don't even try to talk about politics unless it has to do with something universal like the rights of disabled or women. I mean how could I bring anything to a conversation about American politics when American politicians that I can actually name from the top of my head can be counted with my fingers and I'm pretty sure all are presidents aside from Hillary Clinton (and I'm not even sure if I wrote that one right which kinda tells a lot.)
There's other stuff too of course, like sometimes when people talk about some school or work trouble or something I find it that I can't really relate as much as I'd like to or that I'm clearly missing something since things are done differently here.
And of course, just the culture in general. It seems that some things that are fine here are considered rude in America and the other way around, so some things might just be plain cultural differences.
And no, I'm not complaining about the amount of Americans here, it's pretty natural on a site where the main language is English and the founder might be American as well, I don't know, but I just wanted to point this out 'cause I feel like they might not always take in to account that not everyone here is an American and the differences between them and some other people here might be about culture differences instead of age gap or autistic misunderstandings. Of course, the rest of us are also likely to forget about cultural differences, it's certainly not just Americans, but since they seem to be a majority I used that as an example.
The point is, people, before you accuse someone of being wrong or say "that's not how it goes", check what country or culture they're from (and remember that there are different cultures inside of a same country, too) and if you can't see it, never just assume where someone is from. The world is a huge place so the chances that you're wrong are high.
