Literally makes no logical sense.
How can our supposed "superior" intellect as humans, allow for such base and primal actions and mentality?
Straight Men should be happy there are gay men running around, because they are less competition for women, but because men are so vain and think that because they have a penis, that we automatically want it and then want to feel some way about it.
Which is probably the reason gay men hang with women ironically, because there's no expectations other than friendship and no judgement, though not to say all women are fag-hags on 100max.
And not to make this erotic, cause it's so not, but often in these cases, our supposedly straight male counterparts always tend to revolve their attacks around the ass. Whether it be beer bottles,baseball bats,chair legs and even their own dicks, why is that? To some systemic level, I believe males who do this are either curious with internalized hate for such curiosity or are thriving off the primitive act of domination through violence or both.
A very interesting phenomena that occurs frequently in the Animal Kingdom, with one crucial element we encompass, and that's premeditation, which requires thought, which in turn requires interest and understanding.
And ironically enough, all this supposed premeditation, it stems from lack of understanding and even a lack of Empathetic rationality, because someone who does disgusting acts such as this, do not only not understand the reason why they're really doing what they're doing, but do not understand Empathy at all and all that it entails, such as understanding someones feelings, the environment, life, moral values, animal's emotions and emotions in general. And without those two things, we have a very dangerous and misguided individual, who can commit these crimes on the premise of their so called "beliefs" and remained justified in their actions for such beliefs and not feel any which way about it morally.
It's really sad and is one of the things that really make me want to not like people sometimes.
