This is what I thought.
If Phillipson thinks this isn’t an appropriate forum to respond, why not say that and make a statement on the issues another way? Or ask people to contact her constituency office, etc? You know, the way politicians usually engage with voters when they take their duty as a MP seriously.
Censorship isn’t a good look for her. It gives the impression she has something to hide and is scared of debate. Or that she isn’t willing to listen or engage in a democratic fashion because she knows best and won’t be told, which is somewhat totalitarian if so. I hope that isn’t really reflective of her approach, but in any case, she isn’t painting herself in a good light here. Someone with some political savvy should step in and advise her on how to engage judiciously.
