In the UK at least, no.
The ones i've interacted with actually seem to focus on the most, to there own determent, on positive coverage of Cuba.
Like I agree, we should support cuba; but every demo you do should not be about Cuba, they will handout leaflets at these demos with anti-china lines in them about the 'Imprealist Chinese', its ridiculous.
I interviewd about joining one a while ago and they asked me to hand out pro-cuba leaflets that had anti-china messaging in it for some reason, in the poorest area of my city. I asked why not focus on stuff people actually know and care about there, like private property and shit.
They just blanked me and asked if id do it, never bothered to engage with them further other than to sometimes read there lit (transphobic, anti-AES for the most part)
Just liberals who covered themselves in a red flag honestly, its more productive for me to engage with renters and work unions in the UK at least.
