Jack got shit on pretty hard in the beginning (deservedly so if I'm honest) at least in part because he is submissive. Now I don't mean that in a sexual way but rather in a social sense. A good example of this can be seen in their early minecraft let's plays when they would do competitions, if Jack saw someone else was close to winning he would give up immediately. Or even how in every other minecraft video instead of going out and doing whatever the video was about like everyone else he would always just stay behind to build a house. Also for some reason he always uses female characters in games, which I always found weird. Jack is also quite childish, with his love of disneyworld and legos and his disdain for yucky vegetables. Combine all of this with his politics, fatness, beard, his love of marvel movies, and the fact that his wife refuses to have sex with him and you have what I believe to be one of the most accurate irl versions of the soyboy/bugman meme in existence (barring the fact that he is not a nintendo fanboy I suppose).
There he is, Jack the Giant Faggot telling you that you should stop racism and give away your guns while he gets paid to sit on his ass and build a video game play house for his friends. Or more recently how you need to stay at home during the pandemic, while he gets paid to sit at home and play video games and order takeout and talk about how he is being a good boy by not going to disneyworld right now.
TL;DR: Jack is a turbofaggot
