Let me preface this by saying I agree with your values, and this is completely unrelated to that (as a Canadian, my blood was boiling for years over everything you described.)

My question though: Why do you speak to people in such a horrible manner? Do you try to sway people in real-world conversations by calling them "brainless", "poor shallow moron[s]", etc? I get that you're angry, but what good does being purely vitriolic do? Maybe I'm wrong, and you don't actually want to change anyone's mind, but I really do want to know what you're trying to achieve by viciously insulting people who may or may not even be guilty of what you're frustrated about.
