You have no clue what the science of the human body can tell you about gender, do you? Gender is something that takes place, happens and lives between your ears, not between your legs. I tell ya about snails. Biology knows all the dirty stories how the Lord organises gender and sex. When a particular sort of snail mates they cling their bodies together. Mating for them is ultra slow as those are animals that move slow, do slow, live slow. While the act of mating takes place between a female and a male the male experiences a very slow hormone driven change. While the mating is still happening he slowly changes from male to fmale which attracts other male to mate with him/her. When enough snails are present they engage in a sort of chain of mating. The first individual is the female, then there is a chain of some gender changing males in various intermediate states of gender all in the course of still mating and the last individuals in that chain an yet unchanged male about to mate with the freshly changing last male that joined the chain. There goes your gender in biology. What does science tell us? Each species developed a particular way and form of gender according to the needs of the species and biology puts gender changing species in front of our eyes all day long. But the sluttiest, most perverted and promiscuous living beings must be bacteria. When bacteria encounter other bacteria, not only of their own kind but also foreign ones, they grow themselves a long penis, penetrate the body of the other individual and exchange genetic material through it. Basically what they do is fucking with everyone, everybody, everywhere and they do not even have any sort of gender at all! When they separate they shrink their penis and eat it. Later on they offer themselves for being penetrated to anybody. Science tells us that the terms male and female represent a state that is neither fixed in a body nor in time. It can be long lasting, it can be as fluent as a few minutes can do. Biology tells us that gender is a human social construction and a word which determines behaviour and roles and expectations rather than a fixed coined state of our genetics or body. Science knows since long that we humans can have a different state of genetics and apparent outer body appearance and a different gender set of mind plus a different social gender. That are four different types of gender in one person and you cannot claim one to be the defining thing over any other. So follow the science and educate yourself. Scientists all over the world worked on this, even misogynistic, homophobic ones and they agree upon the entire body of evidence.
