Are you aware that the TRAs regularly shout and have signs accusing the women at the let women speak events of being child abusers?
It's really not clear, which group was being accused of being paedophiles...you seem to automatically assume its aimed at the TRAs of being paedophiles. Why is that your first thought!
What is clear is that two groups, the women there just to talk, and the TRAs, there to shout and protest have both accused the other side of child abuse, not paedophilia, but child abuse, different things. but more in connection, as far as I'm aware, to women thinking medicating and surgically altering children is child abuse and the TRAs regularly accusing the women of abusing children by not wanting them medicated and surgically altered and immediately affirmed as the other sex.
The guys with the sign knew both groups, and others would be there, how the hell should anyone but them know why they choose that event or who their sign was aimed at?
Given how little you seem to know for sure why is it you choose to immediately assume the TRAs are most likely to be the paedophiles mentioned in the sign?
Why do you assume from this one sign that those men were there to support the women?
Why are you making these big unsubstantiated leaps in connecting things?
