That's a valuable article and I have bookmarked it. What particularly struck me was this paragraph:
People attending and speaking are also targeted. A common tactic is to send messages to their employers accusing them of transphobia and inciting hatred. Personal details are posted online. At the meetings, we’ve had activists arrive with their faces covered, shouting and swearing at women as they arrive and leave. Some of our conversations are about domestic violence and abuse: they are now held while people outside bang drums, having sworn at the women on their way in.
The italics, mine, remind me of when I went for my abortion and there were religious people outside saying the rosary and handing out disgusting leaflets. It's done to intimidate. And it's, in my view, an act of violence, ensuring that people shut up.
