You need to take a closer look at those complaining to see what their true party affiliation is. The ones I have seen "complaining that the country is getting 'less white'" would spit blood and knives at you if you dared to call them "Republican". The GOP is more evil than Clinton to them.
I do agree with you that those who think only white is right are allowed too much of a platform here on FR.
Last week at a meeting of conservative/libertarian leaders one leader tried to scare us about immigration with the phrases "People who look like us" and "People who don't look like us". He apologized and excepted the lady next to him of Hispanic anscestry as if she were an immigrant. It never occurred to him that she was born in Illinois. Her parents in Michigan. Their parents for who knows how many generations in Texas. She may have been the most American of anyone in the room.
The rest of us in the room, both libertarian and conservative, tried to get him to see the error of his ways....without success. The pro-life leader pointed out that he had the least American lineage in the room. We all pointed out that the Hispanics we knew were pro-life, pro-capital punishment, pro-self-defense, pro-traditional family, and voted for Bush and local Republicans. They hate paying taxes and hate the DemocRAT PRI Party of Mexico, love the PAN Republican Party of Mexico and usually elect Republican governors of Puerto Rico. (OK, so those Puerto Rican governors are RINO's...just like Illinois. But they do have the R label.)
If the media had been at the meeting, they would have quoted the one racist and ignored that 20+ others who took him on.
At liberal meetings on abortion, affordable housing, etc. Nearly 1/3 of the liberals were just as racist as that one conservative. The media reported on these liberal meetings omitting the racist remarks. The stories were carefully edited of non-liberal views (eg mine) to best educate readers to the need for the liberal program.
The most common racist remarks by liberals were minorities were not smart enough to find housing. Hispanics were not smart enough to make proper family planning choices and needed special help with that. They were not talking about welfare moms. They were talking about college educated minority hospital nurses and medical technicians, engineers at Motorola, police and firefighters.
