Discrimination is good. We discriminate all the time. We promote people who work harder than people who don't. That's discriminating against lazy people. We love people who love us and hate people who hate us. That's discrimination against people who hate us. We help people we love more than we help strangers. That's discrimination against strangers. We generally value family over strangers. That's discrimination based on familial status. Once you realize that humans discriminate against other humans every waking moment you realize that the leftist only wants to outlaw certain types of discrimination of which they disapprove in their ongoing war against everything that is good and natural.
