It's such fundamentally flawed thinking. Rapists don't rape because they can't get sex any other way. That's what incels would have us believe - that rape happens because women are frigid meanies and drive men to desperation - but it's arrant nonsense.
Rapists rape because they like it. They enjoy our fear, our powerlessness, the struggling and tears and the feeling of total dominance and control. Often normal consensual sex doesn't hit the spot for them no matter how much of it is available. Rape really isn't that closely related to consensual sex. It's much more like beating the shit out of someone, or verbally abusing someone until they're a quivering mess. It's an act of violence, it's about power, and it absolutely isn't something only sex-starved desperate men do.
