That's debatable. I know a lot of conservative people. Even the ones who are not extreme (i.e. regular folks that believe in liberty) have a tendency to feel (perhaps rightly so) persecuted by the political correctness in the country/world.

Some people may turn to Gab with the feeling that it's the lesser of the evils, or the only place they can feel free from the vice grip of the power elite, but unfortunately that particular environment turns out to be not such a great role model. There are going to be breeding grounds for such views as long as there is an Internet, but those breeding grounds will grow in population in proportion to the additional prohibitions on speech imposed by the mainstream Internet platforms.
