So I was wondering does it make sense that my parents still don't know about this website even though I came out to them and they excepted me?
Yeah, it makes sense. They've already accepted you so if they don't know, that's ok. And if they find out about it later then that's ok too.
I like the fact that I'm anonymous on here. I haven't told anyone I'm out to that I'm active on these forums. If they found out, I wouldn't really mind -- I haven't posted anything I'm ashamed of. I'd just be a bit uncomfortable, because I'm a private person in general. I definitely wouldn't say it's weird not to tell them. Only tell them if you want to.
Yeah, it's definitely fine for them to not know about this site. The only reason my parents know about it is because I'm on staff that way I can tell them when I'm doing stuff on the site so they won't bother me. If I wasn't on staff, they probably wouldn't know about this site.
