So, my two reactions: 1) duh 2) but, proving cause vs. effect seems tricky here, since which states legalized was in no way assigned randomly. An accelerating decline in antigay bias would be exactly what we should expect to happen around the time the legislature or courts see which way the wind is blowing, and legalize gay marriage. Not that I disbelieve the conclusion, but this doesn't seem like it would be very convincing evidence if I weren't already convinced.
