Having unpleasant experience with some rude person regardless of their skin color is not the same as systematic racism and discrimination against the entire group of people. It’s not even in the same category. Being poor and unable to buy something while others can isn’t in the same category as racism and discrimination against African-Americans, Latino, anti-semitism etc Let’s not downplay racism.

Claiming that there is a discrimination against whites in the US because someone said something to someone is so uncalled for. And why bringing up Obama again? That’s uncalled for. The person came here upset about racism. Let’s not tell her that it goes both ways.

By this logic people have rights to be bigots and racists because they are afraid of other people. Xenophobia and lack of knowledge is no excuse for racism and bigotry

In 2020 people have plenty of opportunities to educate themselves and get familiar with the topic. Not knowing what’s what or being afraid was an excuse in the past. Not a valid excuse anymore. Time to get on with a program. Let’s move from old backwards times
