It's not about superiority in that example. It'seems about giving women an Avenue to compete in basketball that would otherwise be cut off from them. It'seems not about all female leagues thinking men are inferior at basketball. Just like not all people for white nationalism are white supramacists.
As for the rest.
You sound like an idiot when you say somebody isn't the brightest bulb on a "tree".
I also don't care about if any race is superior and if so which race is it? If I had to guess, I would say yes racial superiorit exists and the Jews have it, but I don't care because I'miss superior personally and that'she what I care about.
Just Google what white nationalism is from an unbiased source, because you clearly have no clue what it is. You think it means an all white society, but still feel qualified to talk on something you are clueless about. You can also stop insinuating I am a white nationa list just because I can consider and understand POVS that are different than my own
