I think the UK has already been through the violence phase. At the time Maria MacLachlan was attacked, the authorities were firmly TWAW and bending over backwards to accommodate these poor, marginalised, stunning-and-brave victims of the worst oppression ever.
It was before Stonewall's role was properly understood, before it became apparent that they and their Champions scheme was behind so much of the pressure to cancel any opposition to their agenda.
Back then, not only was Maria assaulted and Paula Lamont bullied off her picket line, but the TRAs would disrupt any event organised. They forced their way into the JamJar and Millwall FC was terrified by TRAs into cancelling another Women's event. That's when bomb threats were happening.
The reason Maria was at Speaker's Corner at all was because the intimidation of Women's events was so bad, they had to meet up first to find out where the next event was being held as they didn't dare publicise it first.
Helen Steel reported a similar tactic to the one used against BillboardChris last week:

As I see it, the turning point came when David Davies MP offered a room at the House of Commons as an alternative, in the name of free speech. Now there was someone in authority giving backing and space for these women to speak - and what a furore he raised for doing that!
More importantly, it brought attention and publicity and the general public began to see and hear what was going on. People were at last able to see these men who claimed to be such put-upon victims - and to discover the revolting backgrounds of some of them.
Jane Fae and Jane's friends were forced to re-think their strategy, drop the more embarrassing TRAs who were giving them such a bad name, and go on a charm offensive.
The difference at the moment between the UK and Canada/Australia/NZ is the authorities and media are no longer as captured and the TRAs, despite all the hard work they put into infiltrating these bodies, are not having it all their own way.
