Has Social Justice Become Too Extreme?

Can Social Justice Go Too Far? Recently a professor gave a presentation about how men are being discriminated against in physics due to ideology and not merit. His talk was pulled from the CERN website due to being offensive.

My opinion is that social justice is great when it helps to promote equality of opportunity. But when we try to regulate for outcome we only end up discriminating against people based on race or gender, among other identities. This means that sometimes the drive for social justice can push us into creating similar laws but in different ways.

We end up in a society promoting people based not on merit but on appearance.
