Hate crimes are more applied to in cases of minority victims (whether it’s a minority race, religion, or sexual orientation) because more acts of hate are perpetuated against these groups. More gays get beaten up, injured, or killed by straight people on the basis of their sexual orientation than the other way around.
Time for a rather sarcastic reduction ab absurdum (feel free go Google this term, if anyone needs it!):
Yeah Reginald Erikson do you remember when all those Protestants in Ireland were going around lynching the Catholic minority, with absolutely no comeback? It’s just as well nobody thought about inventing an Irish Republican terrorist group so that the Catholic minority could join in the fun too.
