My grandparents immigrated here from Japan. From what I've heard from Dad, they weren't always so open. But having grown up in a fairly conservative country, his parents didn't accept his sexuality straight away or the fact he does drag. Mom's parents were less so. I'm lucky by the time I came out, both times, it was to a very accepting family. I think a lot of that was my dad paving the way for me. I don't know where you're from or your own sexuality, but I get cultural differences.
I know that if you're not part of the community, the prejudice might not be as visible to you. Because it exists everywhere. Can people marry someone of the same sex where you're from? Because it's only legal in a few dozen countries. And that's a form of prejudice, keeping people from getting married because of their gender. Or I've only been able to very recently change my ID to reflect my gender. And only a couple of states, let alone the whole country, recognize my gender. Many people don't think anyone outside of the binary even exist. So, that's also a form of prejudice. How easy would it be for someone that's nonbinary be able to get their official documents changed there to reflect that?
