It’s not shaming gays to publish their names as donors.
It doesn’t have to be the full profit, just a portion.
The left will claim that they did not consent to being published. That will be the basis for the lawsuit - and in the current climate, I expect they win.
Diminishing the profit of any small business these days means the business is likely at risk.
Essentially, this proposal is denying our side something in order to hurt the other guy. It’s the reverse of the anti-gun crowd screaming about gun control because bad (liberal) people keep invading disarmed target zones.
That’s my opinion, and a selection of my reasons for holding it, at any rate.
