Or DL could look at the equalities act and offer men an equivalent male-only session.
A simple solution but people seem to be against any suggestion of a male-only session and more in favour of complex solutions, such as men hunting the bad men, men organising a campaign against DL etc. It already appears to be esculating.
Time and time we see female-only events (with no equivalent male-only events) which leads to men attempting to find ways against it, either demanding it be shut down, identifying as women etc.
(I've never heard of men complaining about Mother's Day, because there is no man alive that is unaware of Father's Day)
