Why am I a nazi? Do you understand the scope of what nazi ideology involves? Probably not.
Am I a racist? Perhaps by some ludicrously broad definition of the term, but not by my definition. I don’t hate anyone or think that my race is superior. I simply don’t ignore the fact that different races of people look different and I believe that whites have an ethical responsibility to produce white children, so that white European beauty won’t disappear.
In your mind, if someone doesn’t want tigers to go extinct, does that make them racist toward lions? If it does then I think you need some education on what “racism” actually means or some psychiatric treatment.
