The state of Nevada does not have the authority to define what "terrorism" is, and the definition they attempted to forward is useless, and attempts to modify the definition presented by the group who is charged with combating terrorism, so yes, ignore the state law of Nevada, because it's incorrect. Unless you're saying that the state of Nevada supersedes federal agencies as relates to terrorism? Is that really the hill you want to die on here?
And no, it's not the same thing, at all.
