They are under a (false) impression that they are the majority and when everyone moves to Parler the broader audience will be on their platform. And twitter will become a place where the left is just talking to each other and agreeing. Of course, as we can all see the reality is completely opposite. On any conservative platform you'll find a narrow audience discussing only one thing - politics. And it's boring to discuss only politics, even to them.

What's the point of twitter if your favorite commentators aren't even on there? That's the issue. There will likely be a mass exodus of other conservative commentators to parler.

Do you see the irony in your comment?

Echo, meet chamber.

For someone like Trump with a bruised ego, being welcomed by everyone like a religious figure can be very appealing I think.
