We do not live in a perfect world. There is discrimination against whites and against blacks, hispanics and asians. But in reality, the discrimination that each group faces is currently relatively minimal and not much worth argueing about or complaining about. No one is being enslaved, or sent to internment camps or segregated by force.
For most people, discrimination is now a minor nuisance for everyone. For example, if every white guy who said what this guy said lost his house, how bad would that be ? Answer is not all that bad. Ditto for the racial slights that the minorities and women get.
I say that people who are complaining are mostly complaining about relatively insignificant things and that includes the people defending this guy, while if he were a minority, he would be getting nominated for a Darwin award.
