Is shutting down dialogue we disagree with counterproductive?

For those who support these recent social media bans, how is silencing those we disagree with going to help the state of discourse in this country? Isn’t it going to simply push these people into more exclusive and more radical echo chambers? Isn’t it going to ensure that we continue to talk past each other and live in different realities? I think we are losing our ability to reason with one another. It has become all about emotion, how things make us feel. Irrationality on all sides.
