The point is that simply because the poster didn't get long Covid, that doesn't mean it's not something that people get. And it doesn't mean it's not attributable to Covid. While these people could be more susceptible to long Covid because they also have some other quality, trying to downplay either Covid or long Covid because of your individual experience is always a bad move.

And the biggest irony is that people will do that to downplay Covid while pushing "vaccines are dangerous" ideology despite far, far more people having taken any vaccine than having gotten Covid. And those people experiencing far far fewer complications from that vaccine.
