Thank you for your reply, but your response is not logical. Mammals are sexually dimorphic. There are only two kinds of sex cells, sperm (small) or ova (large) in mammals. Sorry, but the argument that you are giving is nonsense and it has nothing to do with what I wrote. I still respect and enjoy discussing this with you. We can agree to disagree and be thankful this great country has freedom of speech, freedom of religion and a culture of free expression. Long live bill of rights and the constitution
