Nature is Sexist

I am truly sorry if I have offended anyone by this statement, but it is true. You may think "HELL no, nature isn't sexist!", but if you were to step outside the box of our own species,  you would begin to see the countless examples of nature being sexist. Take, for instance, the praying mantises of the mantid order. The female is much larger than the male, and often will eat the male after or even during mating. Same goes for many spiders. When there was an orb web spider perched between two bushes in my front yard, a vibrant yellow-white and black pattern suspended above the ground on it's web, I noticed a wee little spider that seemed to be caught on the end of the web. Then I realized that the spider looked strikingly similar- it was a male. The poor guy was oly about 1/4 to 1/6 of the female's size. This size sexism nature dishes out to animals isn't just limited to insects- many predatory bird and fish species follow this trend as well- just not nearly as much as the poor spiders. In almost every species, though, females are much more likely to pass on their genes any given male. Now if nature is sexist, and obviously created differences, why is it so wrong to point them out to people? It's a fact that women have less muscle mass, consume more calories , and have bone problems from having children and having their period about every month. Men have more muscle mass, can go bald, are more suseptible to X-chromosome genetic diseases, and usually don't live as long as women do. Is it wrong to not assign a woman a job that doesn't involve heavy loads, is it wrong to have the man pay more for his incurance? Whether you like it or not, nature is sexist.
