A woman is absolutely a threat to another human. Any animal that size is. That you think women are harmless is ironically, misogyny.
There's a couple of.good books about this - Delusions of Gender by Fine and Sex, Lies, and Brain Scans. Basically we have implicit and explicit biases in how we expect people to perform roles. However, these biases aren't based in fact. When we police other people's behaviors based on these biases, or otherwise force others into roles we've developed, it's bad/abusive.
Women are a special type of role, because that role generally means they have babies (ofc we all know many women who don't have babies). The ownership of their baby making ability is likely why men created the patriarchy, to endanger women by other men, to force women into proximity of whatever man was able to support them. This, and the narrative that men should fuck as soon as they feel any sexual urges because that's "being a man," form the basis for their abuse of women over thousands of years.
Imagine how damaged all our mitochondrial DNA is from our mothers because of this, generations of trauma. And further, the eggs that made up YOU, were inside your mom as a baby, when she was inside HER mom. Meaning your grandma's stress during and before pregnancy with your mom, had a direct impact on you as an egg. And further further, you get 100% of your cells from your mother, and 50% of your DNA. But every cell of life in your body came from your mother. Her stress and abuse has caused damage to the human condition imo and it is therefore vital to treat women well even if you only care about men.
And a key piece of taking good care of humans, is freedom and bodily autonomy, which form the basis for respect in most animal species.
Which is why misogyny hates all of that and why misogynists also tend to like hurting animals too.
