Gab.com seems to be fine to me. Are you sure you aren’t being overly sensitive? The entire point of free speech is being able to speak your mind without being censored. Gab does have serious boundaries about what is over the line of free speech though.

No, I’m not being overly sensitive. I don’t do porn and I don’t hang out with neoNazis (hate porn) and I refuse to associate with them on a wild west free speech site.
I guess it might be a little different if I was called to try to educate them on the folly of blaming and hating all Jews for all the perceived evils of the world, but I don’t have the time or the energy to deal with all that hate.
Trying to plant seeds and get liberals to start thinking is difficult enough especially when sites like Twitter, Instagram, etc. showdowbans conservatives to keep liberals from reading posts.
