Racism today is black and white mostly because types like Shartpon fan the flames of racism. But back then racism was white vs non-white. Today whites and blacks are the main focus of racism but only because Sharpton has been in power.
So yes today it's the case. It wasn't always the case. The people who say that are totally stupid.
You're limiting your perception of racism in the US to what is displayed in the media, and even then, you are completely ignoring the fact that the top GOP candidate right now said he wants to deport all immigrant Latinos. Especially in the Southwest, for example, you still see police brutality mainly towards Hispanics and definitely Natives.
