Maybe those who disagree with you think that you should make a more subtle argument. For those who are convalescent, the risk / benefit ratio of the vaccine is very different than for someone who is immunologically naive. And, to my knowledge, the vaccines have not been carefully validated in a convalescent population, on the same level as the clinical trials on which their efficacy estimates are founded. The idea of getting an illness and then immediately double vaccinating oneself against it should give any rational person pause. This is at very least marginally beneficial, and at worst downright risky. A single dose might make sense, but there should be no rush to apply one. The chance of an otherwise healthy COVID-19 convalescent person ending up hospitalized from reinfection appears to be almost immeasurably low. But the risk of a severe reaction to the vaccine is low but not immeasurable. And it could be worse for someone whose immune system is primed against the vaccine, but that's also not clear.
