None of us are going to hell. Just because you are catholic doesn’t mean gay is bad. No where in the Bible does it specifically say that homosexual people are going to hell. Coming out to your parents isn’t important you don’t have to come out to your parents if you don’t want you. It’s your decision whether or not to come out or not. You only “go to hell” if you “sin” but if you believe you are going to hell then you can think that way. It’s just the way you and many other people interpret their religion and the ridiculous things that are said in the Bible.
Truscum are people who think dysphoria is an essential component of being trans and anyone who doesn’t experience it is fake, “appropriating transness”, a “transtrender”, etc. They very often exclude non-binary and agender people as well and terfs is Trans-Exclusionary Radical Feminist. That group of feminists that claims that trans women aren’t really women, as biological determinism is only a fallacy when it used against them, not when they use it against others. Sorry I actually had to look this up because I’ve never heard those terms before.
The person might be gay/bi/pan and might not know it yet it all depends on someone to define who/what they are.
