> Hairdressing is extremely political.

It's not. You don't have to evaluate their political opinion to evaluate the quality of the hairstyles. You can just look at their work. Whether the hairdresser is on the left or right, he/she can't and won't force a hairstyle on you which you don't want.

> As for the car mechanic example, I wouldn't be black and have my car "repaired" by a racist who would overcharge me out of spite and could sabotage my brake lines.

This is ridiculous. You could equally have chosen an example of you as an old white man, with a woke car mechanic who overcharges you and sabotages your brake lines out of spite. But you didn't. Because that would be just as absurd. But you only see your political enemy, right-wing people, as evil, not left-wing people, your political allies. That this is extreme political bias I need not point out.
