I've yet to see any hard data on this "subliminal suggestion" trick having any greater impact than a statistical blip in the sales of coke and popcorn in the movie theater.
It ain't like single frame ads have people spending the kids college fund to buy Audis.
I guarantee you suggesting it has a nefarious impact breeds more "chicken little" contempt for social conservatives than it breeds homosexuals.
Why are you so interested in breeding homosexuals?
Is there something wrong with objecting to sexual imagery being placed in products intended for children?
Perhaps you like that connection being made?
