Quite so, Dick, but blocking someone on Facebook is a choice in the same way as not taking the vaccine is a choice. Telling the world that you're not having the vaccine is also a choice, as is telling the world that you'll block a vaccine-refuser. Whilst it's a free country, I'd suggest that vaccine-refusers would be better served if they kept it to themselves. All too often, they go large with their prejudiced and ill-informed views, and the last thing we want, in my opinion, is for their vexatious assertions to be sowing doubt and fear. There's nothing tolerant about that.
