Western society has been led by whites and has a millenia of history perpetrating racism. They kept slaves, conquered native peoples, and plundered the wealth of countless nations. They also developed science, agriculture, art, music and sport.
Should we have emulated the militant Japanese? Dynasties murdering and raping seasonally within their borders and then getting on boats to rape and other people in distant lands? Chinese were similarly barbaric but a touch more civil and self isolating.
African nations were feudal gangs at their highest point and remain so today. Dont get me started on the American natives. Those poor hippie Hopi, still cry a little when i think of what happened to them. Its like ol yeller but with more peaceful drum circles. Any smaller tribe that came across the Aztec were tortured and killed then raped.
If we are going to cancel Western culture, what are we replacing it with? For all the ills of Western society it has always been a cultural melting pot. Rising primitive nations to being less so. A force of advancement of all humanity. For all its ills I can't name a superior culture.
