Gender obliteration is actually highly typical of media reporting, and certainly isn’t exclusive to reports on crimes of misogyny. Words like “suspect”, “victim”, “shooter”, et cetera are all chosen for their relative neutrality. Information changes, the facts aren’t clear at first, misconceptions crop up. This is all very normal when reporting in the immediate aftermath of a crisis.
That said, in my opinion this is a mental health issue, not a gender politics issue. The motivation of the madman is secondary to the fact that their illness was allowed to develop - that in the end, society failed to get this person help before they hurt themself and others.
It doesn’t matter which particular group of society someone chooses to blame for their own unhappiness. If it wasn’t women (or in the opposite case men, rare as that might be), it’d be some other minority, or some other perceived transgressor against their happiness. The specific target doesn’t matter so much as having someone to blame.
Misogyny sucks just as much as any other social ill, but in cases like this it isn’t the cause of the tragedy so much as the outlet for the discontent that leads to it. The mentally ill will always find some justification for their actions.
Even if we could cure all cultural social ills tomorrow, we’d still have shootings like this - they’d just have less “convenient” rationales behind them. Ending misogyny is a goal worth working toward on its own, but if we want to avoid shootings like these we need to do more - we need to get mentally ill people the help they need before people end up dead.
