I know its a difficult subject with no easy answer.
What do you mean? What's the difficult subject?
Over 96% of sexual offences are committed by men. That doesn't mean the ≈ 3% by women don't matter.
In fact, the rarity means it's more likely to get pressure coverage. "Man bites dog" effect.
If you think the sentence was too lax because she's a woman, Julie Bindel and others can demonstrate many cases when the sentences for women were harsher because we judge women who are "unnatural" more than we do men.
Or you could look at the young lads of 13 and 14 raping and filming 13 year old girls. They were spared prison recently until a public outcry caused the sentences to be reassessed.
I'm not trying to be difficult, I just don't really understand what point you're trying to make.
