Why are women part of Islam?

When you see what the Afghans did to Farkhunda, you must ask yourself why are women Muslim? I don't think they should be, in fact I think every woman on this world should leave religion. No religion gives them equality or rights. Its disgusting as men, that we allow other men to treat women ( our mothers, daughters, sisters, wives ) as such. We have no claim to superiority with our current beliefs and actions. The muslim religion from MMM perspective must change before we can expect women to join. Women of the world....please quit religion. It does you harm. Demand your rights as a human being first. We mourn her loss, send our condolences to her family, and beg forgiveness from her sex for the behavior of our sex.
