The first post, from his X feed, called it a "violent, abusive act" for a trans-identified male to be in a female-only space. He suggested: "Make a scene, call the cops and if all else fails punch him in the balls."
He then wrote on Substack that during his police interview following the arrest, "I explained that the 'punch' tweet was a serious point made with a joke", and that it was about "the height difference between men and women... and certainly not a call to violence".
His second post from X appeared to be an aerial shot of a group of protesters in a town centre, and he called it "a photo you can smell".
The third expressed his views, in which he said "I hate them", referring to "misogynists and homophobes", adding an expletive.

Yeah, that's how it works. Incite violence internationally, and you can get arrested when you travel to a country where inciting violence is illegal. But he's closely associated with the UK (his ex-wife is English, and they lived there for at least part of their marriage; I imagine their children live with her (because his behaviour has been such that most courts would not give him custody of children). Most of his TV work has been with British TV companies).
I feel like Gappy here way back on Page 2 (and over a year ago) hit the nail on the head here. By his own admission his obsession cost him his marriage and his home life, and also his career. He's indeed a liability. His former brother in law (James Serafinowicz, don't know about Peter) at one point and finally told him publicly to calm down on Twitter (and tweeted to someone else that the family had tried talking to him for years).
He trawled dating apps (who advertise on registration that they are trans friendly/allow trans people there) and posted pictures of the people there claiming they're trying to trick women or whatever. Calls anyone who is vaguely an ally or friend to trans people "groomers" (implying they're peaedophiles). Claimed to be railing against men who "speak over women" yet shouted down the many women who are fine with trans people.
Trying not to say this pejoratively, but the man is in deep need of therapy. Not for his opinions, but his behaviour.
