However , Pay Attention to Yourselves and All The Flock says "If you stay overnight in the house of a known homosexual that is grounds for disfelowshipping "- so it depends on the level of association
In all fairness it also says if you stay over night in the house of a known hetrosexual of the opposite sex that is grounds for disfellowshiping too. I am not trying to show that JWs are "nicer" to homosexuals but just trying to contrast they are pretty dang mean to hetrosexuals too.
