I'll preface this by saying that I don't think electorialism will be our liberation, but it is a tool which is available to us.
Reform (fash) or Restore (broke from Reform for not being fash enough) could likely win the next General Election and things would, in the absolute best case, continue on a very dark trajectory. A Restore policy is "re-migration" (yes, it's as bad as it sounds), so the worst case is much worse. The Greens are lib of course, but they have some decent policies (anti-NATO, anti-imperialist, anti-racist, anti-landlord, pro-trans) and are the leftmost party capable of winning a General Election (Your Party is cooked, and the various socialist and communist parties are very small). So, for now, I support them. I'm aware that many of their good policies will magically evaporate if they get into power, but they are still the least bad option by a significant margin.
I'm getting involved in some much better orgs already, but I still have spare time that I'd like to put to use. So, I went to a local Green Party meeting recently with the hope of taking part in some local organising to raise their profile and perhaps meet some comrades who feel similarly. They had some vegan food options, and I didn't get any overt transphobia, but there were was casual ableism, authoritarianism apologia, and very little talk of actual substance. It certainly didn't seem that anyone there was a comrade and, overall, I'm a bit put off by them.
Do I suck it up and work with them anyway? I can spare the time right now so it's not like it's taking away from anything better. But they're very lib.
Do you engage in any electorialism, and would you recommend it?
If you're confident enough in your own political analysis that you're sure you can get involved without becoming a lib yourself, and if you have a solid idea of how to avoid it sucking up all your organizing capacity, then I say go for it.
Also if I'm guessing right that you're talking about Green Party of England and Wales then it might be worth looking into who the specific people are locally, they (much more so than Scottish Green Party) seem to have a bunch of people who liked the ecofascist origins of the party and aren't so interested in the recent turn to the left.
