"You do not believe, obviously because you're a cop defender."

The fact that you call me a "cop defender" goes a long way to explain why you find yourself in these types of situations. For some reason, you are going around with a chip on your shoulder (you dislike cops and like to accuse them of being racist when they treat you badly). Understand this! There are good cops and there are bad cops! And yes, some are racist, but that does not mean that all bad cops are racist.

"pressed on me multiple times asking the same questions, they asked me roughly 10x.

Asking questions is not the same as accusing.

"If I said no the first time then they should have stopped pressing me, don't you think?""

Not necessarily! After the 2nd or 3rd time, did "you" suggest that you take a breathalyzer if they did not believe you? Yes, I think that if they asked the same questions over and over, those were not very good cops. But, that does not make them racist by any stretch of the imagination.

"accuse me of being under the influence"

Asking if you were drinking is NOT the same as accusing you of doing so.
