Widespread prevalence of sexual bonds between males (I insist not homosexuality) has been proved beyond doubt amongst wild animals.

Now, the ball is in the court of self-defined heterosexuals. It is their moral duty to prove that heterosexuality indeed does exist in nature.....when all the evidence emphatically points otherwise.

And if they cannot validate it through nature, then the practise of 'dating' (that is neither found in the nature nor in non-western societies) should be banned. Male-female relationships should be limited only to procreation. Casual male-female relationships or love affairs should be made entirely illegal. And all intrusions in the male-only societies by planting females into them, in order to establish a heterosexual order, should be removed. So that we can live in the way that nature has meant us to.
