I think it's about scale. If you as a single individual discriminate, no big deal. If a nation or a large corporation discriminates, it causes serious problems.

I think it's about scale. If you as a single individual discriminate, no big deal. If a nation or a large corporation discriminates, it causes serious problems. Also, it's somewhat OK to discriminate against behavior that can be changed. So businesses are OK to be discriminated against, they are after all human creation. But we shouldn't discriminate on the basis of race or sex or ethnicity, because these are impossible to change.
