It's just another symptom of hating the only people in the world that mattered. No different to 'Muh Gay Greeks' or 'Romans were actually gay chud' where if you take even a few minutes to actually look into the sources that people give for this, it's all bullshit; the Greek and romans had a lot words for gays, all of them negative, and they would torture them if they found out they existed. Reminds me a lot of the idea about the settlement of America always portraying the pioneers as dirty unwashed inbred morons. The most accurate account of the OK Corral - from Earp if I recall correctly - involves him talking about passing his second favourite ice cream parlour; these weren't wooden sheds in a dirt patch. Our ancestors weren't idiots, they weren't dirt scratching retards. They just didn't know everything that we do right now.
