So i've read the full thread and the homophobia you linked and to be fair to the author... I think Achillean (the author of the twitter thread) has had his tweet's meaning twisted to make YD look worse than she is, either purposefully or not.
Now, I'm not saying YD is all good, there's definitely some deep rooted racism in her, and she messed up when she doxxed the illegal poster of her work. However, regarding the homophobia claim -- just the homophobia claim -- according to Achillean's google translation of YD's message, YD says:
"Why do you call me a killer what?
Whom did I threaten to kill?
Do you know what doxxing mean?
Answer well
Why do gays hate me?
What did I do to gays?
You'll welcome anyone stealing yours what? do I have to do that?
It's the first time I've seen a dirty and crazy gay like you.
I'll have to prepare evidence of who I threatened to kill and who I read.
I know who you are
Don't provoke me any more"
Each new line is a new message sent by YD to Achillean and there was no answer from Achillean in between YD's messages.
Now clearly the translation is of poor quality, and some sentences don't make much sense without more context. However, we can speculate that YD is answering Achillean's call out about YD doxxing someone and consequentially threatening that person's life.
I don't really know where the "Why do gays hate me?" as I haven't seen anything related to that in the mess that is the twitter thread, but somewhere maybe someone claimed Gays hate her? Not sure, but ultimately that's not the interesting part.
