Those words and accent is understood by more than a hundred million people, and that number is going to increase manifold in the coming decades. So if you need to communicate with this large group of people, it's better that you learn to understand them, or it will be your fault for not understanding.
Take your racism somewhere else.
Thick accents are frustrating in any language. I have had to work hard on removing my American accent when learning Korean; it made understanding what I was saying much easier for everyone.
I think what people take issue with is when native speakers (who only speak 1 language, and maybe 1 local dialect of it) start demanding things from ESL/EFL learners.
We have the Internet now, IMO it's only a matter of time until we naturally converge to a universal dialect. It will be a long time, but still.
I didn't advocate "hating" anyone. On the other hand, you showed up and declared me a "racist" for no reason. Maybe you should listen to your own advice and not jump the gun and hate the person you're talking to.
