I agree with you about the political agitation but I would say its becoming less of an issue on Gab. Parler was quite toxic. However, I prefer MSN messenger style chatrooms, so I use Telegram mostly which has now reached 500 million daily active users.
These platforms aren't just filled with people banned from facebook anymore, and will become less political as time goes on
When they open up digital marketing on a platform thats less saturated, that will be the real test though. If Gab can do digital marketing decently corporations will start paying them money and stop criticising them so openly.

I feel like one of the defects in most of our discourse these days (from any position, on any subject) is an almost complete disregard for trying to understand opposing views (and even a lack of concern that ones assumptions about the opposition might not be entirely correct).
