Having met hard rightwing guys in real life I can honestly say they hate incels just as much as the left, and are often a lot more vocal about it. They'll tolerate them to some degree as political allies, but the ones I've met were always very vocal on shitting on my features. Have had such people flat out just take the piss out of my face and straight up call me a genetic failure, feeling this constant never ending need to put 'inferior' men in their place.
Dunno why some incels think these people are their allies, they're just as bad if not worse than the left, just more forward about it. They'll usually whiteknight hard for women as a form of masculine posturing, it's fucking awful.
