‘I’m not a racist, but..’
Yes, you are. Any sentence following this phrase will erase any doubt about you being racist. You are. Starting your sentence this way does not allow you to make any xenophobic comment. It’s like insulting someone and then saying ‘no offense’. Discrimination of any kind is inexcusable behavior. How dare you judge over anyone but yourself, judging over other people is a merit not a single person in this world has earned or will ever earn.
