Man vs woman?

Equality is an attribute that is difficult to achieve between any two beings. Only the sum of mathematical products can be equal when both sets on either side of the equal sign cancel out each other. The case of equality between the male and female gender has been a source of many debates and contention. If we liken equality with similarity, it is difficult to see how a man and a woman can be equal. Even the physiological and chemical compositions of both sexes are different. In the best of senses, even two men cannot be of equal character and composition. To stretch it further, even identical twins are not equal in all respects. What I think we should focus on is giving both sexes (male and female) equal opportunities so each can apply his/her attributes in maximising the opportunities. But to think that a man is equal to a woman is a fallacy. What do you think?
