Of course I agree with the motion. I'm a thinking person with a reasonable understanding of the history of the region. I'm assuming you are too, but I hate to break it to you, you aren't most people.

Most people don't understand that Zionism ≠ Judaism and this motion will absolutely not help in their education. It will alienate them, and the media will have more ammo to paint us with the "extreme crazies" brush. Worse still, people within the party who have joined, perhaps even as their first foray into politics are going to feel alienated. The party will appear to have been co-opted by a bunch of masturbatory academics, bent on spending time and resources defining a word that has no effect other than to piss people off and alienate them. Indeed that's all the party's been talking about over the last few days: the fact that this motion is meaningless. So what have we accomplished exactly?

This is a classic case of the Left's favourite pastimes: purity tests and virtue signalling. Now everyone who pushed for this meaningless exercise can pat themselves on the back for being enlightened and they can look down on everyone who opposed it, abstained, or dared to clarify its meaning as Polanski has done here. Then, when the taste of that passes, they can get back to sabotaging any real work (which requires cooperation, something these people cannot understand) by choosing a new group of people to alienate.

Next up: the meat-eaters. It's bad for the animals and the environment. Fuck those guys. Let's pass a motion declaring meat-eating evil. Actually, that's not good enough. Roll the pansy-assed vegetarians in there because they lack the conviction of proper vegans.

This is what this sort of politics breeds, and it doesn't stop until you have a party of just 8 people who think they're better than everyone else while giving the other 7 the side-eye.

Politics is about community and working with others — others who may not agree with you on everything, who may not have made the same journey you have (yet?) to come to the same conclusions, but you have enough in common to pull together to get things done. These people have done the opposite. They've driven a wedge into the party for zero benefit, to (as you say) "filter out" people they don't like. Palestinians won't benefit from a bunch of Britons defining a word. They would have benefitted from the blockage of arms sales to Israel, but they've set back any progress we could have possibly had on that now.

It's just so dumb, and selfish, and navel-gazing. And the reaction here to Polanski, rejecting him if he should dare do anything other than to embrace this idiot motion... it's just so counterproductive.
