At face value, that statement does seem true to me.
On matters of free speech I dont agree. The wonderful (IMNSHO) thing about the protections in the US is that even though hate groups are allowed to publish, so are my favorite rabbis. I’m a believer in sunshine as a cure here. “Bad” ideas are best exposed, not hidden. Once out in the sunlight they can be countered.
The above is part of why I find “hate speech” laws both laughable and sad at the same time. Generally the laws are toothless but it lets some people feel they have done something about the problem. The thing is, no law will change people’s thoughts.
