Discussing something that exists and is a detriment to our society makes it more prevalent? Please describe the logic behind that statement. You obviously have no clue what racism is and what the most important aspects of its manifestations are. It's not a race card, it is a reality that whites benefit by fact of their whiteness in the overwhelmingly majority of situations in our society on account of their whiteness. The biggest factor with regard to racism is what happens as a result.
African-Americans calling fellow African-Americans by the "N word" isn't racist, just as a white person calling another white person a cracker isn't. However, either group addressing the other by such terms would definitely be racist. However, and the big point you miss, is that the manifestation of racism against minorities has had far bigger social, economic, and judicial consequences both historically and to this day.
Furthermore, for those trying to justify white racism by pointing out that minorities are also racist, give it a rest. Everyone in our country(and probably in the world) knows that the results are very different when whites are racist against minorities and vice versa. When white males start going to jail in disproportionate numbers with longer sentences, white people reach glass ceilings because of being white, can't get into a university or get harassed and made to feel like a second class citizen because of their lack of pigmentation, then you might have a point. For now though, you don't. When these things become part of our social fabric, judicial system, and economic reality, then you can complain. Until then though, you should stop blaming minorities and looking for reasons to perpetuate racial inequality and stereotypes.
