"Um, and only radicals would escort him out of the building? okaaaaaaay."
After roasting him of course 
"I agree that liberals would be more likely to engage and educate though, rather than evict immediately."
Absolutely, and I'm not going to say that this is wrong, but it definately means that he will have successfully derailed the agenda to 'what about men'.
"My apparently long term failing as a feminist is wanting to gather as many people to the cause as possible, whether they be women, men or trans."
I'm not accusing you of failing, or judging you, but I have personally found the presence of men uncomfortable within feminist organising. It is something experiential rather than theoretical that made this the case for me. If you are able to think, speak and act perfectly at ease with men in your midst - then good for you. Some of us find their presence intrusive, dominating and voyeuristic, or at best - superfluous. Particularly organising around porn culture, etc, where they simply don't know quite how it feels to be born female into this degrading torrent of woman-hating.
Anyway, I have no beef with liberal feminists organising (in fact I have often stood side by side with liberals in many an action- most even), as long as they don't try to stop radical feminists from organising - which is of course rare-more the case of liberals siding with transactivists who want to silence and prevent radicals meeting.
Happy birthday to your little one!
