I have an account on Gab Social. I don’t spend much time on the site but when I do check in there I see lots of interesting content, much of which I’m unlikely to see elsewhere. I also see some content that I think is garbage but I don’t worry about that. I’m grateful Gab exists as a site where people won’t be deplatformed for having non-leftist opinions.
The way I see it, just avoid the topic “Israel” for starters; that seems to be where most of the anti-Semites hang out.
