@MirandainSouthwark I'm too far away to attend, but all power to you!
Beforehand, be sure to take instruction from The Righteous on the correct manner to conduct yourself during any mild registration of your disagreement with The Right Side of History. Perhaps keeping your gaze demurely downcast, speaking in a gentle murmur using only the mildest tones and words from the lexicon of permissible non-heated language, hands held open and low, and with a careful balance of detached calm (to display your credibility as a cogitative being who has considered the issue logically) combined with sufficient indications of delicate dismay (to convey your emotional authenticity which will nevertheless be dismissed because you're not of the caste whose emotions are deemed important).
Also, remember that if there is a small number of protesters, this undeniably demonstrates that nobody objects and society supports female humans being compelled to remove their clothing in the presence of male humans, whilst if there's a large number of protesters, this undeniably demonstrates an organised mass bullying fake news campaign and society supports female humans being compelled to remove their clothing in the presence of male humans. The actual definition of small or large numbers is entirely down to The Righteous on a completely fluid basis.
If at any point the police are called, this self-evidently demonstrates that you have failed to adhere to the correct manner of conduct, confirms your condemnation to The Wrong Side of History and furthermore society supports female humans being compelled to remove their clothing in the presence of male humans.
