There's a difference between expressing an opinion and being rude and name calling. You call people greedy bastards and vile excuses for human beings. How can you expect anything good to come from that? I would also avoid bringing up politics and religion at a casual meeting where you are just getting to know someone. Obviously, if you want to build a more serious relationship, you will bring up your personal opinions, but I think there is a way to do it without insulting others.
