The founder on gab has been on here calling other commenters "cucks" and "gullible morons". And telling a mod "Cry about it" when it was objected. Free speech is about ideas, not being a dick.

You want to personally try to have civilized discussions where you resolve thorny issues that people are passionate about, and may hold utterly objectionable views about. Any given person should do that even if only from self-interest; why waste your life trolling?
The entire Gab application promotes an intellectual sewer, and that's because its business model (same as Twitter's) rewards bad behavior.
But "free speech" in the context of a protection is generally about needing to protect the speech of people who aren't polite, who have objectionable views, etc. And that's because they are still human beings and, absent material harm, have an inalienable right to self-expression.
And people object to their behavior, specifically their political ideology. I don't think anyone has mentioned "inherent defects," whatever those would be.
But there is a problem with free speech absolutist sites like 4chan and Gab in that they attract all of the bad actors that are banned from traditional media for their fringe beliefs.
I'm really interested in finding a solution to this. To make a free speech platform that attracts conventional users but allows for fringe discussion as well. The only thing I can really think of is for established platforms like youtube and twitter to do away with any rules limiting speech (with exceptions for material that is illegal). They already have a base of conventional users that wouldn't leave. I don't think this will happen though.
