The מנחת אלעזר says that we pasken like R. Meir, not his wife.
In this case we are referring to a group that are not only חוטא ומחטיא , which is NOT the case with Reb Mier's wife.
Also, they shouldn't be considered a minority group. do we consider people with pedophilia a minority??? Dictionary defines pedophilia "a psychiatric disorder in which an adult has fantasies about or engages in acts with a prepubescent child"
