Quick question…..what do you mean by “persons are not viewed as being sufficiently capable”Exactly. Like all contracts, marriage requires legally qualified consent. Minors and certain persons are not viewed as being sufficiently capable of providing consent.
Because a whole hell of a lot of doctors say trans people are mentally unstable ergo not sufficiently capable to consent to marriage, same goes for plenty of qualified and top doctors say homosexuals are also mentally unstable. So once again thanks for seeing the light
