Whatever problem your describing, the answer isn't to control people
How you fight is tricky and i don't agree that censorship is the right fix in the long run, but i don't think the person you are replying to thinks that either, it's just one easy way to combat some of it.
Trump got elected because people were tired of "politicians" and because Hillary messed up her campaign. Seriously: She was so close to winning it anyway that I like to think it was her calling a large chunk of her voter pool a "basked of deplorables" that got it over the edge.
In that case, sorry for that.
