I know why they've elected her. She does say some 'based' things and has pushed back against the gender madness. The main reason, I suspect, is that being black immigrant woman disarms the leftist accusations of the "isms" and the "phobes", which the Tory party seem to care about so much.
This to me misses the point. Imagine that you are playing a board game where the stakes are that your opponent wins everything- your money, liberty and home. You allow them to set the board and then allow them to tell you what moves you're allowed to make. "Aha!", you say, "I've found a move where you can't take my piece!", ignoring the fact that your opponent will just change the rules whenever they want.
That's what the Tories just did, but I am Jack's complete lack of surprise at this point.
