Is it really that mysterious? I think the argument can be made that it's too lenient of a sentence, and if the roles were reversed her boyfriend would get a steeper sentence. I'm not saying that's the case, even if it does seem too light for bullying someone into killing themselves. It also doesn't mean that doesn't happen.
I still don't get the point. At least, linking to that story without commentary doesn't match up with the "I am a free thinker, released from the shackles of politics" narrative.
Mostly, there doesn't seem to be much substance to a counterargument (why there needs to be a counterargument is questionable to begin with) if you have to cherry pick case studies that suggest imbalance in sentencing. While that's pretty bad, it seems a bit deaf to the big picture. "Women go to jail for less time than men for heinous crimes" isn't much of a point, or a counterargument, when the discussion is about discriminatory practices against women, who for most of human history were treated as chattel instead of individuals.
You can certainly argue for equality in sentencing, but I don't understand why this needs to come alongside an anti-feminist agenda.
(This is also ignoring that sentencing terms are rarely determined by women, and you may want to have a think on why women are punished less severely. A few minutes on that task may lead you to the realization that societal perspectives on women and their place in violent/immoral behaviour are largely based on a man's perspective, i.e. that a woman is less capable, less equivalent to a man.)
It is easy to sentence a woman to less time than a man when many people today still see a woman as "just" a woman. It's still a widely held belief that women are soft, delicate, and more pure (from a moral sense) than men. Subtle and subconscious biases affect how we treat people, especially when there are deep stereotypes involved. Some take this to an extreme (wherein you see women portrayed as succubi, witches, hellcats, etc) while others take it the other way (wherein you see sympathy and pity because you can't punish a woman as harshly as a man). Either one is a harmful perception, and either one comes with problematic implications in the long term for women. They are always seen in contrast to men, either weaker or as irreparably corrupted. A woman is rarely an individual, not in the true sense, and they are often reduced to whatever perspective a man has on women as a concept.
But somehow this translates to a nefarious women's plot against men for you. I don't really get it.
