Here’s an idea. What if instead of left/right wing, you’d sort ideas into useful and useless buckets, given that the context of these labels will change depending on your use case. X is useful for Y, but useless for Z. Ideally, you are tooling around with pro-social ideas for your governance or societal organization frameworks, which is a necessity if you’re optimizing for freedom, morality or ethics. Sadly, in lieu…
Are racism, misogyny, and superstition useful or useless? Now one could argue that those things are not right or left wing. There is no epistemology for what any given ideology -- political or religious -- consists of. An apologist can simply deny that "negative" things are part of their ideology.
Someone can just call you racist, misogynist, or whatever. Those labels don’t mean anything anymore because they’re used as weapons to shut down anyone who is ideologically opposed to you. Are some people racist or misogynistic, yes. But when you use these labels carelessly for anyone who says something you don’t like, you pave the way for actual racists and misogynists because they can call you unreasonable, inaccurate or unreliable.
And what is an apologist, exactly? If you’re unable to come up with a different way to look at something, that doesn’t make someone else who looks at the same thing in a different way an apologist. These are just political smears of the incurious or browbeaters.
Just because the leftists happen to align themselves with pro-social values that I prefer, like anti-racism or anti-misogyny, doesn’t mean they’re right about everything.
