No, mostly it's a platform for avoiding trolls and ads.

If you feel your POV is being avoided, ask yourself WHY. In the marketplace of ideas, not all ideas are created equal. "Freedom of speech" doesn't mean everyone has to listen, agree, or care. If you're just looking for a place to spar, there are sites designed for debate.

On the fediverse, the only constraint to free speech I've seen is that it shouldn't be hateful or attack other users. That, right there, is its biggest appeal.
