Exactly. These posts have been nothing but mindless hate. You guys should kill yourselves right away for the good mankind. Humans have deeper psychological conflicts going on that stem from confusion of where we come from and why we're here. Reducing "problems" down to groups of people is apart of the bigger human problem of peaceful co-existance with any lifeform regardless of the differences we percieve in each other.
So to answer your question: I think the biggest problem for mankind right now- is mankind itself. We are our own test. If you think singling out a group of people to unilaterally hate is going to somehow lead you progress- I suggest you pick up a fucking history book.
