Hunter x hunter fans

So like hxh is one of my favorite anime and I want to see other people with the same taste as me. I also have some questions if you don't mind answering?

1. What's your favorite arc? Personally I really liked Greed island or York new

2. Do you think Gon's a good main character?

3. When did hating on hxh became a thing? I mean if you have a good reason it's fine but like some people just do it because?? now I'm just getting my feels hurt..
