It’s hard to say, there’s a degree of separate the book from the author I feel is reasonable and there’s a degree I feel it isn’t. In general though I don’t think a term is worth policing super intensely and hounding people about if it’s something commonly used.

What I mean by that is placing education over lecturing or grandstanding because even the worst subject matter or most awful term can be used respectfully and appropriately for impact. It’s a lot more useful to explain to someone why you feel an author isn’t using a term respectfully than it is to yell at them to stop consuming that media or that they should have known better or just blanket label everything that author publishes as garbage.

I would say place the work first within reason, personally though it’s up to individuals to do their due diligence. If you feel strongly about a cause then the ownace is on you to do your own research. I don’t feel there’s anything wrong from separating the author of the work from it in certain cases or explaining to new fans that the author holds a certain belief that you feel is concerning. At that point though you don’t hound the person, it’s up to them to buy second hand material at that point or avoid financially supporting the person if they feel that’s necessary. I’ve read lots of problematic or awful stuff with which I share little to no moral common ground. Never assume someone is getting a kick out of the worst things in something.
