Impeding the ease by which these views are spread is the goal. To expand on the analogy from earlier in the thread: You wouldn't suggest people taste test coke, pepsi, and drain cleaner. You'd make sure drain cleaner was not on the same table, and definitely not drinkable.
Maher will impede the ease of these ideas by delegitimizing them through rational argument. To your analogy, it's the difference between there being three bottles and actively trying to remove one saying don't look at it, verses there being three bottles and arguing that one of them will kill you if you drink it. And in the meantime, there are people saying that the drain cleaner bottle is actually the good one and that people trying to remove it are forcing their opinions on you because they can't/don't have a rational argument. Milo makes these claims all the time when the protests happen. Violence and silencing is often viewed as a tactic that people use if they
don't have good arguments, not necessarily a tactic used to minimize highly dangerous ideas. The optics of silencing and violence are not in your favor, especially when these tactics are explicitly and constantly publicized and spinned into bigger stories than they would've been otherwise. The protesting and forced silencing are literally bringing
more attention to Milo than he would otherwise get.
There's a basic refusal to acknowledge fascism isn't a viable stance in a free, democratic society, here. The idea is an inherently bad one. It's destructive to the very nature of freedom. This isn't a debatable tenet you're advocating get its time in the spotlight. It's a poison.
There's a basic refusal to acknowledge that
people need to be convinced that authoritarianism is a bad form of government.
Your argument seems to boil down to the idea that if Milo gets to say "I won because you did this" that he actually won because... what? Because he said so? I asked earlier why people are so inclined to set the bar for winning so unfathomably low and cheap?
He isn't winning because he says "I won," he's winning because Trump is now President. Is that not obvious?
What possible frame of reference are you using in which "Lets discuss the positive tenets of my fascist, racist, white supremacist viewpoint" is the fair and rational way towards a better future? Why does Milo, of all people, get to freely, and without any significant challenge, get to set the believable terms of rationality in response to leftist pushback to his abhorrent views? Who cedes that power to him, and what good is it to do so?
I didn't say there were positive tenants of a fascist, racist, white supremacist viewpoint. In fact I've explicitly said multiple times that aggressive debate will prove that such ideas are garbage. But refusing to let the debate happen while yelling "Nazi!" isn't how to convince non-voters or Republican-leaning voters to push back against bad policy.
