No one is concerned with the freedom of expression implications here? "Aliens" have been a claim people have brought up for decades.
And until a few days without causing damage. This "joke" mobilized air forces throughout the world, almost caused a diplomatic incident with Mexico, brought widespread panic, and we're not even considering that some people might have committed suicide over this (I wouldn't be surprised if that was the case). The fact that we never bothered to punish it before shouldn't really stop us, not when these incidents bring so many consequences.
