Buddy,
You may find that it is easier to get something going than you imagen - you will probably have to start
very small hovever and take a long term view.
Buy a few mens rights books. I have a link from my own site as does Darren in
www.cooltools4men.com. As you read them you may think of other people who should too.
Do not be too pushy. Just say you have read an interesting book and lend it to them.
I do not know your age but you will meet more and more wounded men as you get older. It is (unfortunately) not hard to find them. Invite one or more to a social outing and just discuss life. This will inevitably involve some of the issues didcussed here.
Congratulations! You have just formed a men's group!!!
Do not worry about a lack of education. When it comes to gender issues this makes you stupid, not wise. I myself an a 42yo security guard.
Men do not like joining organizations unless they really understand what they are joining. Nobody knows what a men's rights group is right now so nobody will join one!
They will be very happy to talk to a man who understands their problems though. Just be a friend and be yourself.
