I agree on the first part about Amber's sexuality, but the second... James Charles has never done anything for any other youtuber, no matter how big, bullied, or young. He interacts with his audience only when one of his 'sisters' dares to criticize something he has done, and slams them on multiple socials to make sure that said person won't be able to show their face around for a few months at least, and then spends at least a week crying about how strong he is because he fights off cyber bullies and all the other meanies on the internet.
He wouldn't consider Amber for even a second, because he couldn't gain anything from her: Shane was on his channel when he was first doing his documentaries and people were watching him religiously, Jeffree was on his channel because he's rich, knows how to operate a businness, and helped him launch his career, Jenna Marbles was there because her subscribers count has been going up quickly in the past months and she's known as a very unproblematic youtuber, and we all know why he was friends with Tati.
What could he gain from a deathfat like Amber, who doesn't have enough subscribers he can try to appeal to nor enough talent so that he can try to steal ideas from her?
Nah, James is a leech that was taught well and knows not to get involved with morbidly obese women who offer nothing but lies about rape and disgusting muckbangs.
