Gay relationships are not unfriendly towards kids, me and some of my friends from school aren't creeped out by gay people, and we are just entering our teenage years. I think SpongeBob liking Squidward is one of the few adult themes left in this show after the movie. Squidward may really dislike SpongeBob, but again, he could secretly love him, there are many deep dark secrets you want to confine in your mind and heart that you wish to keep to yourself unless you are ready to give out that information. Besides there are some signs that could be possible about Squidward, like when he acted all nice and loving in Breath of Fresh Squidward, and he also said "SpongeBob, no matter what I've said, I've always sort of liked you" in The Graveyard Shift. He does act nice towards SpongeBob too on rare occasions. He could be just hating on SpongeBob to hide his secrets like Helga Pataki did in Hey Arnold!
As for SpongeBob its obvious he likes Squidward with definite signs past the movie, like saying I like Squidward in a flirty tone, and him always wanting to be around Squidward, he also acted funny towards him in Boating Buddies.
Yes i like Brokeback Mountain and The Village People, and I think SpongeBob and Squidward are one good perfect slash pairing, no matter how crazy it sounds. Hey everyone's got their own opinions, and I happen to think and want SpongeBob and Squidward to be together and be happy and go out to places. I love the whole idea of SpongeWard or SquidBob, some people are gay its a fact of life, and a lot of people know about it these days, even some kids. Me thinking SpongeBob and Squidward are meant to be in love is my own personal opinion, no matter how creepy it sounds, and I would love it if some future episodes came with SpongeBob and Squidward admitting their true feelings on how they love each other.
