LF used to be my MP. DH and I had an exchange with her after, for the one and time, we voted for her/LibDem, and they promptly jumped into bed with the Tories. She was pretty nasty when we expressed our dismay about that.
She's very typical of the type who are deeply unpleasant, very privileged and want people to know their place, but dresses this up with liberal credentials. You can always tell, because in their mind, their deigning to support you (Lady Bountiful as a pp said), is the most valuable thing they have brought to the liberal agenda, and they put a lot more value on that than the actual people they purport to stand up for. And this is why, for the likes of LF, nothing more than fawning gratitude for the LFs of this world will do. It's an, "I lowered myself to stand up for you, now you owe me absolute loyalty and respect, and woe betide you have an opinion of your own" type attitude. You only hold this attitude if you didn't really care for the people you are now turning on, but were just using them to make yourself look good. And they react like LF has - pure anger from the bully pulpit and inserting themselves into a conversation nobody was having with them. All because they think every woman of colour owes them personally. They try to elevate themselves above the people who do actually suffer from prejudice, marginalisation etc, to "teach" them where they have gone wrong, to belittle their experiences and contributions, and to re-establish themselves at the top of the tree, where they always intended to stay, because that's the ultimate game. The LFs stay at the top, the NAs get her support, and yes, maybe a bit of relief, but they must know their place and show sufficient gratitude.
I see a parallel between this exchange between Nimko Ali and Lynne Featherstone and the one between Kemi Badenoch and Caroline Noakes the other week.
