When hes a white male and doesnt understand the repression he faces isn't the only important.
For real though, repressing minorities is a tool which at the moment capitalists use to get days of unemployed, wage slaves or to split the working class. By fighting the capitalists you can help minorities, but you dont nessescarily do so.
It's important to remember, that discrimination predates capitalism and won't automatically perish by fighting the class war but by fighting it in solidarity and activley addressing all kinds of unfair and unethical behaviour together.
If you make that face when a women talks about being denied an abortion or a subaltern not able to participate in discourse, you haven't understood solidarity and won't get very far.
