Maybe. But if you're trigger happy to block/mute everyone you come across, it also means that you're incredibly weak to any difference of opinion. It basically makes you the bigot that can't stand people who don't fit a very narrow mold.
Of course, just blocking a few people doesn't make you that. But it also isn't good for you. With every person you reject ever interacting with, you become more and more sensitive to viewpoints different then your own. At first you'll start by blocking neo-nazis, then you advance to people making nazi jokes, then to people who think nationalism is good, to fundamental Christians, to vocal Christians in general etc. And of course the same goes if you're on the right. (I used the left-wing as an example, because that's the political side I'm more familiar with).
If someone in particular is specifically bothering you, harassing you, and just telling them "I'm not interested in talking to you" doesn't work, then blocking/muting them is a great tool you can/should use. But if you use it for anything else than a last resort, or if you find yourself using it constantly, then maybe consider that there's a problem of communication coming from you too.
And as a suggestion, every once in a while, completely clear your block/mute list. I wouldn't be surprised if after just a few months, anyone that was trying to annoy you or harass you, has long moved on.
