For me, it’s hard to say one or the other is worse. It might depend on circumstances. Is someone making a false claim of rape worse than someone raping someone, or worse than a child rapist, serial rapist, etc? In damage collectively done to all victims, quite possibly. However, the intention of the false witness isn’t usually to delegitimize the claims of other victims. It’s usually shortsited and desperate - a desire to avoid social consequences or to punish the accused. I suspect such false claims are also more common among a younger, naive, immature population. It’s fucked up and selfish, surely. As fucked up as feeling you have the right to use another person’s body for your own physical pleasure or to assert dominance or whatever shit goes through a rapists mind? I don’t know.

Frankly, I’ve never been the victim or perpetrator of either crime, nor have I even been in a situation where either crossed my mind. All I’m qualified to say is that I wish neither crimes would happen to anyone.
