how can you discuss covid with people with this opinion
I don't think you'll be able to have any kind of a discussion with them and therefore I probably wouldn't bother.
Some people on the Internet are just wrong (cue xkcd link) and there's no little or no point attempting to "help" them.
I'd just assume that someone else with more time and energy will attempt to fight them, and I'd just move on.
Think you are right, probably you are right. As there is always a but with me, lots of people have died and this attitude I find angering/upsetting.
