Negative coverage is bound to be the result if you impose yourself at the front of an organised parade, usurping the lead place given to NHS staff.
Handing out leaflets that explicitly accuse the trans movement and LGBT politics of coercing lesbians to have sex with men (not just some nasty TRAs mind, the whole trans movement) and that refer to ' so-called "trans women" ' at the very front of a parade intended to celebrate inclusivity and diversity seems calculated to cause maximum negative publicity.
Especially given that literature handed out during the parade is subject to foresight by the parade organisers for everyone else.
I can see you've got plenty of attention, and I'm sure that makes you feel very well pleased with the action.
You may have over-egged the pudding though. The banner saying transactivism erases lesbians for instance. Yes, some transactivists are behaving inexcusably towards lesbians, but marching at the front with a banner accusing a whole movement of being complicit is not going to help you get the ear of the masses.
And before you jump on me, no I do not think it's ok to tell anyone they must have sex or consider having sex with anyone else or any other class of person and no I do not condone rape culture or the erasure of lesbians.
