Then the post wouldn't have meaning because that's a universally agreed upon moral sentiment on its face. The post is targeting people who would rather take offense to recent discourse rather than slowing down and considering how this moral sentiment applies to the situation. Without specifying 'women' and 'men' the post would not have contextual meaning.
You're free to make your own 'inclusive' meme that states the obvious, but the people this meme is targeted toward would see it as obvious and not consider how it pertains to their behavior.
