OK there have been a few sides to take. I figure 8 ways among Civil War (Iron Man vs. Cap), Schism (Cyclops vs. Wolverine) and Avengers vs X-Men (Avengers vs. X-Men). Yeah, that last one was repetitive. Anyway, to summarize:
Iron Man: Register your superpowers, for safety.
Captain America: No registration, for freedom.
Cyclops: Stay together. Use kids to defend Utopia
Wolverine: Re-start the school in Westchester
Avengers vs. X-Men
Avengers: Detain Hope for analysis of Phoenix Force
X-Men: How about, uh, no.
