I'd say 'You'd hope this would wake people up to just how unelectable Corbyn and Labour currently are', but who cares at this point, it's far too late.
People need to give their heads a wobble when it comes to the future of Labour. Corbyn fans, you are in a very small bubble, deluding yourselves into thinking you have a 'massive' movement behind you. You don't, you really, really don't.
Well, if you're happy for the Sun and the Daily Mail to call the shots forever, then fine. Think you need to figure out who the real enemy is to be honest mate, but it's not like you're the only one. There is a majority of apathetic, demotivated and fundamentally right-wing people in the country that do not examine anything critically, because they're happy to be spoon-fed by tabloid journalism, who pretend to be on their side while actively participating in making their lives worse.
It's not a case of simply just being a 'Corbyn fan' (as much as you really like to push this personality cult idea), these are people that are sick of the inequality in this country, and he is the closest we'll get to somebody doing something about it because unlike other politicians, he actually cares about it. You make wanting a fairer society seem like it's something you should feel embarrassed about.
