Leigh, effectively what your post says, is that you just come to the onlineopinion site to express an opinion, while refusing to take on board the opinions of others.
You also say you have no interest in debate, which loosely translated means you just don't want to have to back up your opinions. You can claim you're being bullied all you want, but all that's happening is people are presenting contrary opinions.
Funnily enough, that happens in a place called 'online opinion'. Of course you don't have to take on board opinions, but whingeing about them is hardly a good look.

redneck - 'leftist shiites'. Very creative. A little extreme perhaps, though I'd argue that categorically damning other races as inferior to whites and asians places you squarely in a fringe category, well outside the mainstream.
Perhaps this is why you say you're reacting to 'people like me' who are perhaps, a little closer to opinions accepted by the mainstream. It must be quite cathartic to be able to use me as an opportunity vent against the many people who condemn your attitude. I hope you're enjoying yourself.

In relation to your argument - you've chosen a snapshot of history which you say supports your argument. I'd say it represents a very narrow view. From the broader sense, how about acknowledging that while western society was mired in the dark ages, non white or asian races in the middle east were well ahead of the ball, and created the foundation for our understanding of medicine and astronomy. At that time in history, Islam was far less authoritarian than Christianity.

The resistance to the melting pot exists now and I concur that it's a problem. Sorry if that doesn't fit your preconceptions.
I'd argue that if you talk to the older immigrants who were living in a different time, those that came off the ships in the aftermath of WW2 became American first and their heritage took a back seat in the rush to carve out a decent life, which was what America offered them instead of the ruins of Europe.
