I live in a very leftist place, and there were always those at climate events demanding "strict vegan diets" however I didn't see these people out in the general world outside of my little leftist bubble, trying to actually get their idea out there.
I agree with Michael Mann that what most of the public only encounters this idea of "strict vegan diets is a required climate solutions" by hearing it from climate denialists poisoning the well of climate action. But I also see this idea online, and in meat space in very isolated areas.
So the idea of "strict vegan diets" is a real idea on the fringe, but its overall effect on climate action has been to turn people against climate action in the US.
an odd place to be a hotbed of vegan advocacy.
Many vegans I know were in fact motivated to that choice by realizing that meetings of humans were in fact "meat space."

It would already help to consume less meat.
It seems to me you focus on vegan diet to use the annoying vegan stereotype for your purposes.
