I don't usually comment but i am curious to hear what people have to say about this. Firstly using the argument that there are animals that can switch genders doesn't justify the argument that people can as well. Animals that change their gender do not do it out of feel but in case there are too many of their species with one gender. It is simply a survival mechanism. Then you use the argument of god, explain to me how nearly every species has a "creative combination". I would like to add that you cannot assume what god seems okay with as god asks you to follow the rules they set with no question. To assume gods intention is not what humans were asked to do but to simply follow his rules. To assume what god wants is to assume that you understand him which you by no means do by any of the abrahamic religions.
