Never once said I don't think or want them to exist.
Here, I'll spell it out. If you didn't know, how someone argues something tells you about their position in relationship to the subject.
"We merely want to exist" this is the argument.
You started with this statement. Either you are going to confirm, or be against the statement here in some form or way. Or use it to make an argument.
This is how it always starts.
"This is how it always starts" is a negative way of phrasing something. It shows frustration.
It was the same with LGB.
And here is the part where you ended up revealing your hand entirely.
You have a negative disposition on LGB(TQ) people.
With this all in mind, it's pretty obvious that
"We merely want to exist" this is the argument.
Should be viewed as you saying
"I disagree with them wanting merely want to exist"
And in which, you demonstrate even further your hatred.
We just want to get married, we just want the same rights" soon ballooned into we want preferential treatment.
Here your making a strawman. LGBTQ don't want preferential treatment. We want to be treated as equals. And you refuse to do so.
People that use the term cis are openly trying to offend you.
Cis means agreeing with assigned gender at birth. It is not offensive.
It slowly spreads like a virus.
And here you demonstrate your hate. Trans people know they are trans at a pretty early age. You refuse to understand that trans isn't a popular thing "corrupting the youth" it's that our understanding of it, and acceptance of it, has.
Gay people used to not be visible, left handed people used to be not visible. Just because it wasn't visible didn't mean it didn't exist.
You're angry at them being visible in society, acting and believing as if they weren't a thing before.
So
Never once said I don't think or want them to exist.
don't go trying to act that I misread you. You demonstrated that you don't want them to exist.
