"When a child is introduced into a very private environment under the complete control of two male abusers the risk soars dramatically...",
I would add:
"When a child is introduced into a very private environment under the complete control of two female abusers the risk soars dramatically...",
and:
"When a child is introduced into a very private environment under the complete control of one femal and one male abuser the risk soars dramatically..."
Surely we are not using "abusers" as an synonym for homosexuals. Are we...?
