Parameters as preface -- I'm not saying that abuse of executive orders is confined to one party. If anybody says a "But Trump did x." or a, "Bush did y." I don't accept that because you're arguing in bad faith.
Biden's executive order regarding gun control is the epitome of stupidity and tyranny; but, what's more, it's the epitome of hubris and self-confidence. That applies both to Biden and any supporters of the order.
Pretty much all executive orders are wrong in regard to process, even if you support what the executive is trying to do. We're not supposed to be a monarchy. One person isn't supposed to be able to decide what does and doesn't land people in jail, or how the legal process should work.
But, this goes beyond that.
Trump is running next year. DeSantis is probably running next year.
If all you "blue no matter who" people believe your own rhetoric, that those options are literally Hitler, and you're supporting these sweeping gun restrictions, you have to have a delusional confidence that Biden is gonna win re-election.
Otherwise, you don't mind being disarmed prior to Hitler taking power, or coming back to power.
