Thankyou for sharing this. I'm sorry to say none of it surprised me. Misogynistic abuse, violence and stalking has historically been brushed under the carpet, despite it being linked to serious violence. Terrorism, lone actor grievance fuelled violence and some murders have it at the bottom of them... but it's ignored.
Female politicians are at major risk from this type of dangerous man. They're public figureheads and have power over others, which this kind of man hates. The sad thing is if a black person was targeted for their ethnicity, I think it would be recognised more; but women are expected to suffer.
