You're free to explain how it is racist. Genetics are not connected to borders. Saying that Mexico is not as nice as the rest of North America is not the same thing as saying OH GOD I HATE MEXICANS THEY ARE INFERIOR TO THE SUPERIOR WHITE AND BLACK AMERKANS.
Calling that racists is about on par with me seriously calling someone racist for talking shit about Mississippi.
If you can't see a difference between the two, then I don't know what to tell you.The problem with Mexico is that it is shit. It is the shit country on a contentment with two superior countries above it. Canada and the United States are objectively better countries.
Perhaps you can debate about it being racist, but it was certainly ignorant.Calling that racists is about on par with me seriously calling someone racist for talking shit about Mississippi.
I am still trying to figure out what a contentment is.
