fascism doesnt play fair in the marketplace of ideas, if you invite a nazi to sit at your table you've made it a nazi table. free speech is necessary and important, but we still draw lines for things like defamation and hate speech. another line is not offering a platform to fascists, they arent entitled to a seat at the table to spread fud.
you're like "but i'm not a nazi" , great, let's keep it that way.
