Great thread and amazing posts from Pooch, Scallops and Donkey.
I do believe critical thinking is necessary for feminism as it is for any other political movement. I think that's the case whether we are writing theory, campaigning and organising, volunteering or fundraising, or just talking to people about issues we care about. If we don't think critically we can end up supporting all sorts of dreadful things.
That doesn't mean we all need to be academic though and I agree, sometimes that gets in the way. I did art and graduated with a head full of postmodernist bullshit which at the time I thought was irrelevant. Sadly it's turned out not to be, it's turned out to be the foundation of some very dangerous harmful ideas.
Most people are capable of critical thinking and I agree it's a life skill you can improve and which will serve you well in all areas of life. That story of the emperor's new clothes - it was a little child who employed critical thinking.
It's questioning whether someone's claims make sense and whether there is any evidence to support them. Whether their arguments are logical. If they are saying 'thing A, therefore thing B' - does thing B actually logically follow from thing A or is there a step (or 10) missing? Or does A have no relation to B at all?
If someone is making an argument that you don't understand it might not be you being thick, it might be that their argument doesn't stand up. Ask them to explain. The majority of arguments that are solid can be put into simpler terms. Those that are built on hot air can't.
though, eh?
