Show me a man who can give Birth and ill accept your concept of equality.
If Akal Purakh has made man and women different, physically, emotionally , chemically, physiologically etc.. then who are we to say man and women are the same.
Notice im not implying man is superior, i am just saying man and women are different, neither is higher or lower, better or worse but different. Each has its own roles, its own purpose. Sant Ji says those who say Women should be able to are, nastik.
Your notion of equality implies man=women, so when it comes to marriage if man and women are equal is man+man or women+women ok, in gurmat?
