Yes these are ad hominem attacks. An attack on the person instead of that persons debating position. It isn't much of an argument, just endless name calling and an element of shoot the messenger
A reasonable discussion might go
Person1. "I don't think this virus will ever go away because science says blah blah blah ..."
Person2. I disagree with your position because other science says blah blah blah. ..."
This is reasonable debate because the people are attacking each others positions but not each other personally
But if person 2 were to say "You're just a dementor, a crab, spreader of negativity, a joy sucker who wants me to put cheese in my milk, seek mental health support" and so on, then it's a way, in their mind, to cancel not only an opinion but the person themselves
There is also the irony of accusing others of negativity by starting a thread dedicated to negative name calling. Infact this is one of the most negative, and divisive, threads I've ever seen on MN and that's saying something
