If you wanted to have a very robust religion don't you think that it would really need to be 2 religions one for males and one for females? Poll: Yes/No ? Think about the relationships between men and women. They don't communicate the same way. They read everything differently. Some people (probably many people) give up on trying to be understood by the other sex. Some never try. Male and female seem to have different interests, a different focus, a different set of problems. Can they truly share the same religion? It seems more like they must have different religions.
I suppose that if a religion were very limited then they could share it, but I'm not talking about just sitting in a park feeding the birds. I'm talking about lifelong commitment and practice and about the ways men and women perceive things differently, grow up differently, choose different activities and have different responsibilities.
Even if you disagree, consider what if the answer were yes? Would this change the way you do things?
