You mean, "repeal Section 230"? Because the entire point of Section 230 is to allow imperfect biased moderation without having to eliminate all user content. Such calls are ridiculous, stupid, or malicious on a host of levels. Making editorial decisions about what to allow on your own private property is core 1A Freedom of Speech, with caselaw dating back to well before the web.
"Editorial effect" is also an utterly meaningless phrase. You probably have some silly politics thing in mind, but moderating against porn or violence also has an "editorial effect". So does having a forum devoted to aircraft or cats. I think trains and birds are great too. But if I want to run a forum specifically about aircraft or cats, I need to be able to delete train or bird posts, and if necessary ban users who won't follow the rules. This is all completely biased and has the editorial effect of shaping the forum to a specific niche of speech, there is nothing common carrier about running a focused forum. And politics could indeed enter into it, what if some political group proposes a law banning aircraft or cats? Rallying and organizing against that could include being biased against those who want to support that law. Colorful and strident invective may be featured. Such is life in a free society.
If you want a soap box that does something else, the law also protects your ability to make that (or to group up to do it or pay someone else to do it or whatever else). And as a practical matter it is now easier and cheaper to do so and get to a potential global audience then at any time in human history (let alone the history of the US). Win the argument in the marketplace of ideas, not using the state monopoly on violence.
