Not exactly: As a matter of material fact, people either verb or don’t verb. You don’t “allegedly” verb unless there’s a real question among third parties. There’s no dispute that they protested. Why did they protest? Maybe their underwear has too low a thread count- who gives a shit? They did the thing. Their motive is not the issue. Whether they were paid to protest is not the issue. Either they protested or they didn’t. The act of protesting isn’t like lying or being a hypocrite, it’s not contingent on intent.
I have nothing against calling into question other people’s motives (I do it all the time) but it’s not related to your use of “allegedly”. I just happen to feel obligated to point out that people who organize protests can be stupid without any malevolent third party. I feel like the Koch Brothers in particular make bad suspects because this isn’t their fight. Sure, they can be real assholes but sometimes a tree falls in a forest and they have nothing to do with it.
