Which is exactly why I go to great pains to point out that I have great sympathy for those that did everything right, and still got screwed over.
But remember that nobody just catches COVID (or the flu, or similar diseases) in a vacuum. They got it from someone else, who got it from someone else, who got it from someone else. There’s a strong probability that someone in your infection ancestry (for lack of a better term) is one of those selfish people that refused to take basic precautions, and if they had taken precautions, you would never have gotten long COVID. We’ll never know who it is, but at least one person out there is probably directly to blame for your long COVID. That person deserves to be mercilessly ridiculed until long after they die.
