I am very uncomfortable with violent imagery on political event/demo promo material because deliberately it sets the tone of forcing through the event aims, on threat of violence and encourages violent knobheads to show up and see how far they can push it.
But especially in this particular context where there is a climate already of women being intimidated by men and women have actually been punched for disagreeing with them on this particular brand of politics.
Maria McLaughlin was punched to the ground at Speakers’ corner by transwoman Tara Wolf and although Tara was found guilty of this attack, in court Maria was forced to use female pronouns for her attacker by the judge

So punchy fists imagery is particularly shit in this context.
Nobody should face threats or violence for being who they are or wearing what they want but that goes exactly the same for trans people and for women and anyone else.
Some threads if anyone wants to read up on intimidation of women by TRAs, just to name a couple:
Bristol Jam jar event in 2018 where women were physically trapped on a staircase by masked TRAs and verbally abused (police did nothing to get them to stop it)

Lesbians kicked out of public events by police just for being there as a peaceful ticket holder:
