I am afraid that you are confused. There is one political party in the US that is attempting censor and even completely silence the speech of anyone that disagrees with anything that they believe by any means necessary including destroying people's lives and livelihood. Citizens didn't boycott parlor. Citizens didn't deplatform Trump.I'm afraid you're conflating two distinct concepts.
Boycotts don't try to ban books and censor speech; lawmakers do that.
Boycotts are simply citizens exercising their right to choose.
