Well, in the case of those that did inject bleach, they don't speak ill of the dead.
If, however, you're trying to claim that Trump was being ironic, you need to rewatch the footage. He genuinely thought he'd had a briliant epiphany and was asking the medical professionals if it had been looked into. Also, irony doesn't work if half of your base are morons (see those that did inject themselves with bleach, those that still believe the election was rigged, those that believe QAnon, etc., etc.).
