Because it's always useful to demagogue conservatives when they merely *peep* about anything to do with culture or *gasp* race. I'm a scientist and therefore not a firm believe in 'race' per se. I do believe in culture tho. I also think my country's culture is superior to all others. In my country it isn't OK to molest young children, slaughter goats in suburban backyards, or use the public sidewalk as a latrine. I understand these are perfectly acceptable practices in *other* cultures but when the members of said *other* culture come to my country I insist they respect *my* country's culture. For this, I have been labeled a racist by the bots. Sad. America is *not* a race, it *is* a culture tho.
My ancestors didn't come here to be *white* but they did come here to be free. Recent immigrants by and large only come here for financial gain and care little about the freedoms the founding fathers fought for so long as their welfare checks arrive on time and their ballots are in a language they prefer.
