That seems a misunderstanding of their argument. I suggest using an LLM, quoting the comment, and discussing with it till your comprehension matches that of the machine. They’re usually pretty good at it, and it appears better than you in this instance.
You seem to be reading things into my words that I didn't say.
I get that more representative is good. I get that FPTP isn't that.
But what I said is, when their complaint is that the Conservatives keep winning, that makes their whole argument suspect.
