I think it is marvellous how mumsnetters don’t seem inclined to accept unsubstantiated rumours about people, we tend to listen, read and make our own minds up.
You have to come to some sort of judgement about someone's views, character, and, well, their own judgement. So far, KJK has yet to let me down, while quite a few others have.
I'm not quite sure what judgement Onnabugeisha is drawing from KJK choosing to use Carl Benjamin's channel. Clearly a huge character flaw is being perceived, assuming it isn't just a general "guilt by association" opportunistic attack, but I'm not sure what.
Personally the main thing I see is someone determined to spread her message to as many people as possible and who clearly prioritises that over what the left-wing bubble will think about that.
I don't have a problem with that.
I can see some left-wing feminists not liking the fact that they're on the same side as right-wingers, but there's not a lot they can do about that. I don't imagine the right-wingers being super thrilled about being on the same side as radical feminists either... But you'll just have to put up with it, or give up and go along with the trans activists.
Not wanting to personally ever come into contact with a right-winger is a perfectly reasonable position, but you have no right to demand it of anyone else, and if you reach the point of refusing to touch anyone who's touched anyone who's touched a right-winger, you're just not going to be very effective, are you?
