There's plenty of extreme harassment, attacks, and "shouting down" coming from the right in response to any ideological disagreement from the left. Worse, explicit calls to violence (that have been answered) and encouragement of hatred from people all the way up and down the chain, from anonymous internet posters to the president. I'm not saying this is worse than the equivalent from the left, but to say it's not there is naive. Additionally, as far as I can tell, nearly all of the major instances of deplatforming of "the right" have really been deplatforming of meaningless hateful garbage or calls to violence that violate terms of service, but have been framed as attacks on the right, which seems like a really awful mischaracterization of the right.
