They don't hate solo players, it's just more fun to play as a team. I am pretty anti-social person but in Destiny I have tons of friends. That is one of the reason I enjoy this game. If you have noone to play with, this game is dull. Solo players are missing a huge chunk of fun. Trust me. You have no idea how fun it is to talk shit while you are doing Trials or the raid with bunch of your internet friends. It is a hell of a good time.
