Well, those thoughts ARE racist.
The thing is that it is true that there are many things called racism. If, for instance, you limit yourself to especulate regarding certain qualities, you are simply using your brain on a polemic subject. If, by the other hand, you are using those ideas to sustain a feeling of hatred or racial superiority toward other groups, then that's an agressive way of racism.
Another possible application of the word might be when, let's say, a white man is extra polite to a black man just because of his skin color, but that's a little bit ridiculous. The situation, however, seems to escalate to extremes such as "talking about about illegal immigrants is racist"...
Let me start by throwing you a hypothesis: what if latino people are actually the superior ones? Taking into consideration that the original skin color was black, or near black, and asians and whites came after that, it should be interesting to notice latinos are the newest "race".
What are they made of?
1. European soldiers and warriors.
2. Natives who survived genocide and wars.
3. African slaves who came from africa and endured a lot.
You might think of what happened in the new continent as some sort of agressive natural selection process, so it shouldn't come as a surprise that our women are big favorites in contests and our people have managed to occupy all kinds of spheres in no time. I think I read there are more Venezuelans at NASA than people from any other country.
What do you think about that? I'm implying evolution at work, meaning that latino people have been taking over white people in relative little time.
Also it is worth noticing that latinos have been populating every continent a lot faster than any other race. Could it be that we, horny as we are usually labeled, end up being the majority in less than a century?
