It doesn't just stop there.
I made a response to that guy in the comments, and that discussion ends to the point where I stopped bothering because he would repeat the same thing.
The thing that I noticed among LRT supporters is that they willfully ignore problems like the odd S-shaped design along 102nd Ave, and they constantly bash on SkyTrain despite the evidence to the contrary. Talking to them is like talking to flat-earthers: they always fabricate, spread, and repeat their lies that the round Earth is a conspiracy even though a simple google search for facts contradicts their beliefs. Of course, LRT supporters don't go to the extremes (except for zweisystem), but the parallelism is still there.
