I'm not saying the popular vote is more valid than the constituency-based system. I'm saying there's more nuance to the situation than "the population wanted Brexit because the Tories got a majority", which is what I thought you were sayin here:

Also, as I recall, there were two elections after the referendum in which UK citizens doubled-down on Brexit by returning the Conservatives to government with landslide victories.

...

In any case, with such sustained support for the Tories post-referendum, it's hard to lay the blame for Brexit at anyone's feet except the UK citizenry itself.

I can't deny the last sentence, but using the election as evidence makes it sound like over half of the country wanted the Conservatives in power, which is demonstrably untrue, that's the only thing I'm arguing against.
