In between

If one insists only to promote practises that are "natural", one can easily, following the course of basic logic, end up criminalizing not only homosexual intercourse, but also numerous sex acts that don't lead to procreation. So, what's the point of oral or anal sex, masturbation et cetera? Or: if a human being is to be natural, then it is unable to intervene; and then, abortion should be illegal, contraception should be illegal, all the kinds of diagnostic procedures during the pregnancy should be banned (because they can lead to abortion); the very concept of interfering with curing and healing is in question, medicine is in question, if you like.

Then again, giving to much credit to a human and culture can also be misleading. Some sexual practises can be just mischievous or simply disgusting -  practises that are not hurting or exploiting other human and/or animal. We're living in a hypersexualized world - kids are  exposed to naked bodies with hypertrophied sexual features from very early days. Sex sells and everything is to be sold to everyone: "Brats" dolls are an example of "sex sells". Too much human intervention spoils, even destroys the nature, as it destroys the "natural" part of a human. We insist on human rights, minority rights, we insist that every being has its value, yet we abort foetuses holding an extra chromosome, yet we insist that a human has to be "useful". We embrace certain types of bodies, colours, shapes and sizes yet we brutally shame and destroy other types. We are not loving humankind in its diversity: we are trying to shape a very certain type of diversity - using media, fashion, plastic surgery, social networks, educational pressure, family planning.

So, when we fight to "save the family values" , "tradition values", "normality", or "diversity", "welfare", "freedom" we are so often soaked with hypocrisy. Sometimes we're just blind or unwilling to see.
The tragedy of being a human is that we're crucified between "nature", and "culture", between being an animal and trying to overcome our animal core. We can't be either one. We are obliged to stay in between, trying to find our spot in million shades.
