"Yet to be convinced" of someone's innocence is (luckily) a far cry from being convinced of his guilt.
You react 'as though' he is guilty of domestic violence. You also 'seem' to view all domestic violence cases as the same (which they aren't). It is true that, sometimes (maybe often), a woman's voice is muffled by the court system. There can also be a significant power imbalance at play - and when you are talking about a high profile sports-person with lots of supporters with vested interests, it 'could be' a case of her voice being squashed in favour of his. However, for every situation like this we also get the other one - where political correctness tells us that NO MATTER WHAT the circumstance, the male is the evil perpetrator, and the female is the innocent victim. In this model, the male voice is completely unheard and the woman's behaviour not even looked at. And, of course, the male is referred to as a grub or other such labels - often totally unjustly. I'm so glad that you are able (through some magical powers of vision) to have made a definitive determination in this case. I'm also glad, for Semi's sake, and the girl's sake, that your determination doesn't mean anything to them.
I think that domestic violence is a horrible problem in society. But it is not exclusively a male problem. And for just as long as we keep viewing it as exclusively a male problem, we will never solve it.
For years, as a kid, I was impacted by sustained and ongoing domestic violence (mostly verbal, sometimes physical) between my mother and my father. Now, I love them both, and I hate to say this, but most of it was my mother's fault. She couldn't help a lot of it because she had a mental illness. But most of it wasn't my father's fault.
Domestic violence is NOT a one-size fits all scenario.
Semi 'might' be a grub. He might just as easily not be. Or he might be a grub in some contexts or situations or times in his life but not in others. Like you. Or me. Or most people. Your black and white view of the world would scare me if not for the fact that most people don't adhere to it. Luckily.
End of rant.
