How does Bla's last post have to do with Avaaz, Smjjames?
Anyways, xriqxa, I don't think that episode wasn't even trying to convey an anti-gay moral. Patrick was pretending to be a girl, and Squidward and Mr. Krabs were attracted to him. So once he finally revealed himself, they were shocked.
It implied that they are hetero, and that they are not attracted to the same sex. That's not anti-gay, in a discriminatory sense.
