She'd be best hoping that her words don't come home to roost.
Perhaps. But if she's as evil as people seem to think, perhaps not. Perhaps she just thinks truth needs stating.
I've never heard of her, don't know anything about her, and don't agree wholeheartedly with her political point, but she has every right to say what she thinks, especially if she thinks that in the long run it will improve things for people with dementia.
I don't see the point in getting all hot under the collar when people say things that are, or could be, manifestly true even though unpleasant. What needs to happen is that people need to implement positive change. If that's her aim then good luck to her.
