All three links you have sent me (though I only had time to scan them, obviously), concluded that there is a significant gap between male and female offenders, that can almost entirely be accounted for by;
1. Women being more likely to plead guilty.
2. Women being statistically more likely to have childcare responsibilities (which it is strictly ILLEGAL to take into account, but seems to happen anyway).
3. Female prisoners being significantly more likely to be mentally ill. (This is statistically true, whether you want it to be or not).
The cases you have cited are horrendous. However, scientifically they don't tell us much, except for a few individual miscarriages of justice picked up by tabloid journalists and anti-feminist websites. That doesn't mean there aren't others out there.
I'm trying to approach this from a position of complete impartiality. The general picture seems to be that there is a bias towards women, because the law and society still see them as the victims. I am completely against this, and I fully support the campaigns for recognition for male victims of domestic violence.
However, I'm not quite sure what you want from this thread. You seem to just be filled with hate. There are many different types of feminist, and some of them are downright misandric, but the vast majority do want equality (though I think the name 'feminist' needs serious rebranding).
It's not the average woman's fault we get sentenced more lightly, and most of us agree with you - I don't see how anyone couldn't.
