If we don't except racism? why do we except sexism? Why is there so much sexism online e.g. Facebook?

[Quo Vadis?]

Because racism is real and is a problem. "Sexism" is a lesbo-invented shaming tactic used to garner women more undeserved special privileges, to silence male opposition to their hate group, and to destroy heterosexual relations. That is why straight people do not take the lesbian hate word, "sexism" seriously at all-- mainly because it does not exist.

"Sexism" is dykespeak for, "Natural heterosexual behavior of the two sexes. Men being proud of being men. Men pointing out the obvious, pervasive, and self-evident flaws and inferiority of women. Women being disallowed from professions of which they are horribly not suited and where it would be dangerous to the general public if they were allowed to work in them. Any attitudes that are based on the natural psychological, biological, physical, and evolutionary differences between males and females, where lesbians delusionally believe that women should be allowed to do anything without being held responsible for their actions."

So basically, the word, "sexism," is an expression of the mentally-illness inherent in lesbianism and that is why no sane person thinks it matters, because it doesn't exist as the sqawking lesbians use it.
