False Rape Accusations are a form of abuse. Rape is also a form of abuse. They are not equivalent, but can certainly lead to the same order of life-destruction magnitude in either case.

Both of these things are relevant in the discussion of consensual sex, and I disagree with your attempt to elevate one position over the other.

Rape is bad because it negates a persons agency over themselves and denies them their basic human rights - false rape accusations also deny a person their basic agency and human rights.

Best way to avoid either case: just don't have sex, i.e. learn the value of abstinence.
