I support free speech but I also don't want flat-earther or nazi-supporting opinion columns in my newspapers/websites. Or at least not more than one a week or so. I don't want to spend my time consuming rubbish, or having a lot of conversations why those columns are rubbish.

The columns can be published sure, but in some fringe publications that I don't have to know about.

I also don't like the idea that all people with rubbish ideas should be able to demand distribution via any popular network/publication/institution. However when someone with rubbish ideas is already known, refusing debates or stuff like that is just silly.

Also it's good to remember that free speech means you shouldn't be persecuted for your words. Not that you can't be disliked or made fun of.
