The wonderful world of flowers alone would disagree. They're are all pretty kinky. And we can't prescribe concepts like male or female to other organisms, because they are human conceptions applied to things that have no need for them. It says more about our societay's expectation of defined sexes than it does the animal when we try to assign binary gender to other things.
Your later example doesn't apply here though. The animosity people feel towards this set is the proof that there is still a lot of anti-l gbt resentment in society. If a company wants to make 6-fingered gloves for a small portion of their audience, no one is going to complain. The company is servicing a small portion of their audience who has gone unrepresented in the market. Similarly, LEGO makes a lgbt set and it's just one in their entire catalog. However, people come crawling out of the woodwork to complain that it's "too political." What's the only difference here? I can't see anything other than people bristling at the idea of l gbt people being treated as equals.
The government isn't forcing companies to make 6 finger gloves. As society moves forward, groups of people are able to see themselves/their needs represented in more products and media. If you don't need a 6 finger glove, then just don't buy it. Complaining about it does nothing but make the 6-finger folk feel unwelcome.
I'm gonna stop here for now though, 'cuz I've said my piece and don't want to make any more waves. I like you guys too much to drag us down any further. Everyone is awesome.
