Then how is it fair to judge them for it?

I mean, it is socially unacceptable to judge people for their race, religion, sexual orientation, looks...but judging someone because they are socially awkward or "lame" is totally acceptable, even among the self proclaimed "social justice warriors". My brother is a perfect example of this, he is constantly ranting about racism, sexism, etc. but at the same time he loves to ridicule and disparage people(mainly other males) for being "lame", socially awkward, unintelligent, for liking the wrong kinds of shows or movies. I cannot wrap my mind around this.

And in my case, along with many others, my undesirable personality is actually the fault of my peers for socially ostracizing me during my school years when I people normally develop social skills and a personality. But somehow it's my fault and nobody else's. Makes so much sense. Do people even have a moral compass?
