There's two main reason why people boycott Disney.
A: Their stance on homosexuality
B: Their subliminal messages
If homosexuality is a big enough issue for you to boycott them, then, by all means, boycott them. We went to DisneyWorld in 2006 and if there were gay people there, they didn't impact our enjoyment of DisneyWorld even a little bit.
Boycotting for so-called subliminal messages in movies that are 20 years old seems a little silly to me. I mean, really, we're worried about a cloud of dust spelling out S-E-X from an 18 year old movie? The horror! What's that "evil" subliminal message supposed to accomplish anyway?
Don't we have better things to do?
