I'm very much of the opinion that if you have something to say, you should say it. And if you are debating someone, you should let them have their say. However, there is a difference between being exposed to differing opinions and having someone attack you online. My time and attention are valuable. If I choose not to have trolls on my social media feeds, that is my prerogative. This becomes an even bigger problem when someone crosses the line from being a jerk to being abusive and/or threatening. I don't often experience that, but others do. Making the choice to block trolls isn't a lack of tenacity, it's an active choice to filter out things that take away your time or energy. Yes, you may fall into the trap of creating an echo chamber (which can be doubly bad if people filter out all criticism), but that's on you to take notice of.
Good point, while I find this tool pretty laughable, I would strongly prefer this approach to a top-down approach on each and every platform, protecting us delicate users from the wild animals of the internet. If people wish to stop up their ears, I say let them!
