Sure many attempt to but not all of them do.

On the right we have people like Ben Shapiro who is Jewish but is best friends with a gay political commontator, who routinely states that he my personally disagree with his friends choices in life, but he values individual freedom more than anything.... Ohhh i just realized this.... do you understand what the key tenants of right vs left are?

the reason why people on the right are fine with people expressing racist views, or views that they disagree with in general is because the further right you go(if you were to look at a political compass), the more personal freedom you have. Leftists by definition are more authoritarian. Communism (complete state control over the economy) being the furthest left you can go, & Anarchy(no govt whatsoever) being the furthest right you can go
