Debanking is a form of social deplatforming that (for now) mostly targets right-wing causes. That's not at all to assert that the bill is wrong or that censorship is right—I'm just clarifying why it's Republicans on the side against censorship, in this context, when in other contexts the roles are flipped.

You can read the bill's author (Kevin Cramer) discussing that bill and his motives for writing it:

> [Senator Kevin Cramer] "...I've heard that one from some pretty big bank presidents - but they get a lot of noise in their left ear and you have activist investors and whatnot that are saying, hey, you know what? We don't like coal. We don't like oil, we don't like natural gas. We don't like private prisons, or we don't like ammunition shops or gun manufacturers or whatever the case might be, the entire category or industry and says, "Well, so we're not going to bank them. We're going to debank them. We're not going to bank them. You're disqualified from getting money from us.”, and they're starving these industries out. And all this really is, in my view, you guys is this is a political agenda where they're utilizing the leverage of the financial services sector to accomplish policy goals that they can't accomplish any other way."
