Exemplary
It does make some kind of point that scrutinizing the presuppositions of an argument¹ is apparently so overwhelming a challenge that all you can do is attack and insult.
It's hardly new, and it's not uncommon. Many conservatives buckle like that; they'll do anything to avoid such scrutiny. The basic idea is that since their argument doesn't work, they need to dilute the discussion, and invective is the best they can come up with: #
435↑,
440↑,
443↑,
446↑,
449↑,
451↑.
The problem for conservatives, of course, is that even basic scrutiny is so dangerous to their argument.
So here's a hint, and not even a pro-tip, just the basics:
When your argument is to moralize about lifestyle choices, don't use identifiable speculation to justify your moralization. Like I said: "simplistic", "blithe platitudes", "history", "circumstance", "mythopoeia".
And the best you can do is make as much rude noise as you can in order to change the subject.

¹ e.g., "rags to riches stories are always incredibly simplistic", "Blithe platitudes about lifestyle choices and living within means are, at this point in history, the sound of failure", "In such circumstances, your complaint … just doesn't work", "the sort of crackpottery that comes from the Boomer-era mythopoeia about liberals and the economy".
