Oppression? No. Calling these sorts of incidents 'oppression' trivializes the suffering of the disenfranchised millions who live in daily fear of beatings, lynching or rape because of their religion or ethnicity, and must try to survive while knowing that others can rob them and destroy their possessions with impunity and they have no legal recourse. You might as well call having to shake hands with a man you don't like 'rape'.

Incidents on the level of those mentioned here are inevitable in any society that has even the slightest degree of diversity. Everyone has been treated badly by members of a different group at some point in their life, and responsible adults are expected to get over it and get on with things.
