I agree with the man’s position. But shouting down candidates isn’t the way to “speak.” Have a quality debate with the man. Challenge him on that.
But shouting so that he can’t be heard? That’s not right.
They followed him on the parade and heckled him. Rudy was not prevented from being heard--he didn't try to speak. He CHOSE not to speak. None of the reports even suggest that Rudy tried to speak or that he was interrupted as some tried to claim. If you have seen reports otherwise, please provide them.
IMO, Rudy saw that his audience was not a friendly one (other reports mention that the firefighters were also present during the parade, heckling him and holding signs) and decided to find an audience more to his liking. He seems to prefer invitation-only townhall meetings where he faces only the loyal Rudy-supporters.
