I have previously lived in the USA, I'm not sure why you assumed I have no experience of that.

In general I would expect someone who speaks the language of the country I live in now at roughly the same level I speak English to have a pretty accurate understanding of what is going on here. It would, frankly, be quite weird to speak the language and have no idea of what is happening here. Of course America is a special case because of how the internet is dominated by US media, commentary and content.
