Discrimination, without context, is necessary in nearly every situation. I must discriminate between bleach and water if I am to live, I must discriminate between walking into fast traffic and when it is safe to cross the road etc…
On a softer level, I discriminate between who I call my wife, and who I don’t, which of my friends is named David and which is named Alex…
And then if I’m employing people I can’t give everyone a job, I have to discriminate to a single person per job.
So, with the taken that to do anythingsome level of common sense discrimination is needed. However, humans cannot be relied upon to not take discrimination to an unfair place, and people must be forced to discriminate fairly.
People also lie, and will straight up tell you to your face they do not discriminate against women from the moment they enter the workforce to their dying day, and yet will, in private, discriminate against women so hard even if it were to destroy everything they hold dear. The only way to prevent that is to force people to discriminate.
