Are you saying none (or few) of those complaining about political correctness are racist? - nope. You 're the one making a claim without evidence (see below).
There is a minority of people today who are racist, is that not so? - but you call many people who complain about PC 'racist'. Sorry, you don't get to do that without providing some kind of evidence in support (opinion polls or other data).
And why are you trying to lump ordinary people together with the minority of racists?
Who have I called racist? - in your own words: The problem is many of those complaining about political correctness are in fact racist or harbor some other harmful ideology - you have no data to back this claim up. Therefore, you'd do well to retract this assertion.
Ironically, someone who is chaffing at being wrongly accused of racism has some small taste of what racism feels like - but why should those who are wrongly accused of racism suffer for what actual racists say and do?
