I noticed pretty much all of that

..except for the chicken analogy, which seems slightly far-fetched (though I admit I can't think of any other symbolism to attach, and it does seem odd enough to warrant a symbolic interpretation), and the homosexualism vs. pedophilia thing. I knew that Sean was gay, but I didn't make the connection between it and gay attitudes towards pedophilia--probably because I didn't fully appreciate the pro-pedophilia overtones of the movie until the very end.

One of my cousins is gay, and on several occasions I've heard him say things about pedophilia that sound very sympatheic. He's an outspoken member of the gay community, though, and I highly doubt that he'd ever jeopardize himself or his cause by saying such things in public. If necesarry, I'm sure that he'd rather attack us than be oppressed just like us. The symbolism fits perfectly...
