It's not just a tankie thing, unless the usage of tankie has expanded since I last checked. Tankie-controlled subreddits were frequented by far more than just tankies. Furthermore, it's not all leftists, or even most leftists I'm accusing of this. My point is that it's bizarre when self-proclaimed leftists do praise the Houthis, precisely because the Houthis are a far-right theocracy.
What else were you contending in my comment? That 'tankies' is a narrower term than 'all leftists'? Or that more than tankies frequented tankie-modded subs back on Reddit? Those seem even more unlikely, but if I was wrong, feel free to tell me which of those you were responding to.
