Shouting someone down is not debate.
In a shout-down the the shouter is revealed as someone with a platform so weak (or the opponent’s so strong) that theirs cannot compete in the marketplace of ideas.
Shouting down is crowdsourced censorship. Let your opponents hang themselves with their own words. Let the audience make their choices.
