Not that I'm attacking anyone here but is this the "not American"-page?

I don't get it. Every question, every post, every discussion is about bashing America. I love American culture, I love the American people, I love their spirit. I'm American inside and out. I may not speak English perfectly but my grandparents and my great-grandparents were American. I just don't get it. It's not okay for someone to bash someone else for race or nation but why is it okay with the Americans? I'm not bothered personally but I'm afraid that it'll be too much for one person in the future.
