I fail to see why. If you get your way, and all the "free speech" people get blocked because everyone else finds them insufferable, then that's exactly what you asked for. It's also incredibly bad taste and rude to suggest that blocking happens because things "hurt your feelings", please never utter that phrase in this context again. That's an extremely trollish way to approach conversation and you need to stop. Disagreement happens for other reasons besides "hurt feelings".
I think you do actually understand though that "just block it" is a bad strategy because this is fundamentally not how humans interact in a large group. Every person can't go through the trouble of vetting every single thing that's being said all the time. At some point you have to trust someone to tell you if someone else is being a jerk or not a jerk. And that's why it's weak to somehow try to turn this into an issue of "social media censorship". If blocking isn't censorship then this isn't censorship either.
