It's my understanding what people are trying to limit here is the spreading of extremism. The theory is that people can be drawn in with what people call "dog whistles" that evade filters and once trust is established, proceed to deliver more extremist messages. These aren't just theories, these are how extremist ideologies get spread around the world, from ISIS to anti-government militias in the US. I think most people are quite agreeable to filters (personal blocks and mutes, etc.) to deal with speech we find unpleasant. What we don't want is for those filters to provide cover for extremist recruiters.
