How many times does the protester tell the police officer "I'm not moving", in the video posted by @Gronk?
I lost count.
The police officer's demeanour and tone doesn't suggest heavy-handedness or partiality. He tries to negotiate and persuade and is rebuffed with "I'm not moving". He did his job thereafter.
To misinterpret and reframe the Resisters action as a "peaceful protest", when they themselves tell the police that their aim was is to hold up the parade, isn't helpful.
A more helpful message is that Pride will not allow gender critical lesbians to march in the parade. As a result, noisy, shouty protesters will appear spontaneously to challenge their exclusion. They will risk arrest and they will have to be removed by force, because they are not going away until Pride agrees to include them.
