(I might as well give my reasons since I am the primary guilty party here)
Your original formulation seemed quite judgmental towards conservatives and got a lot of pushback. Most objectionable, to my view, was the suggestion that Dems could just "let conservative voters die off".
To quote your exact words:
I know this is horrible to say, but wouldn't that "weeding out" process result in fewer Republicans voting in 2022? Or at least wiser and smarter constituents?
Rather than editing myself, which I avoid most of the time, I suggested a removal, but you did perfunctory edits at most, resulting in, at your last iteration:
I know this is horrible to say, but wouldn't that "weeding out" process possibly result in citizens voting left-wing in 2022? i.e. older, wiser and better-informed constituents?
The question got closed and I tried to salvage it. I did this by linking to a Fox article quoting Tucker Carlson rather than some Newsmaxx quack, and tried to remove your attempts at shifting blame to conservatives in your question. Attempts which probably caused all those downvotes and close votes.
Is this the best reformulation? Possibly not. And I apologize for changing the question's original intent, whether or not that intent was good or not. Like I said, I don't like editing people and, like you, I feel a strong sense of ownership towards my questions. I did not do this lightly and my profile has a very limited history of edits, I usually stick to VTC/VTD.
I got pushback on several of my edits. However my edits wouldn't have been necessary in the first place if you hadn't been so intent on politicizing a public health policy question. The fact that it is a governmental policy question makes it worthwhile for SE.Po, not the fact that you felt the need to blame Republicans and conservatives and phrased it accordingly.
Note also that, aside from myself, there were 3 other answers that explained policy rationale for pushing vaccinations to reluctant populations, without mentioning political parties, starting from your original formulation.
Last, to quote your meta question:
What I am seeing is older users pushing their agenda riding on my question.
Let's not play the naive 500 rep user game here. You have plenty of rep on other sites of this exchange, you know questions can get pushback if they show evidence of bias, it should not have to be explained to you.
