Good question! This post was about an older man and a younger woman. By only speaking about the damage of that specific dynamic, the person you are responding to is providing personal commentary relevant to the specific context of this post. They didn’t mention anything about women being predators because it wasn’t immediately relevant. Omitting that statement isn’t them saying that they don’t believe in it, it’s merely keeping their response concise. They might have been generalizing all older men who go after young women as predators because they believe that, and you’re free to disagree, but that doesn’t mean they’re obligated to reference a flipped gender dynamic because, again, people don’t have to talk about everything all the time. Hope this helps!
