what criteria must be passed, must be met, for a person to be male? same question regarding female? is it one thing, or multiple things, that a person must have or be to be female or male, and what is that one thing, or what are those things? answering those questions, and proving you're right about the answers, instead of merely offering your opinion which differs from millions and is similar to millions, will get folks a lot closer to agreeing on the answer to the question, how many, if any, genders are there? right? that's my guess anyway. not sure, but that's my guess.
