No....but well maybe

Case in point 😉

most leftists are not

Most are not, and many deride those who are. Exhibit A: imgflip.com/m/GunsKillPeople

Most? Many?
Most recent meme on that is from 2 months ago. The front page goes back 7 months. Nearly all posts are from one member, with a handful from another.

Also, the primary contributor to that stream, despite appearing to be exceedingly far left, is actually the alt of an exceedingly far right member who went quiet a couple of years ago.

Which one? One of the ones that moderates P2?

Yes, and a ton of other streams, many just like the one you posted where that profile is either the primary or soul poster.

How does this prove that leftists don't actually support gun control?

You posted a link to a dormant stream that functioned as an outlet for one primary user, with a few from another. The assertion is yours, not mine. The position is yours to question, not for me to explain your claims to you.

You're losing track of what you yourself are saying, going from one angle to another, questioning me about your own questions and assertions.
