OP I agree with you. I said on another thread recently that the radical feminists on here have the option of sticking to their hard line attitudes, preaching to each other or as you suggest, concentrate on the important issues.
Recently we have seen Martina Navratilova, Sharron Davies and Piers Morgan addressing trans issues in a moderate, concise, clear and easy to understand way. I expect large swathes of the general public who have little or no interest in feminism or trans issues looked at what they said and thought- "yes that makes sense".
This demonstration to the casual observer (which is the majority of the public) just looks bonkers.
And if this is the "telling feminists they are feministing wrong" - I couldn't care less about telling feminists how to practice their beliefs but most people are not feminists. That particular accusation, tbh when used, comes across to me as nothing more than an attempt to shut up a poster expressing a view which departs from the concensus.
If preaching to a small choir of like minded women is what radical feminists want, then carry on with this sort of stuff. If what radical feminists want is the general public to get involved, this sort of demonstration isn't it.
