ok, ok, ok... fine: we'll play your game for a moment.
first: there is no such thing as a "World citizen"
the word "citizen" is a political designator, and there is no world government.
your use of such a spurious term marked you as a possible troll.
"YOU have all had it too easy on Earth over the last few hundred thousand years apart from Russia!"
1. *I* have only been around for the last 34 years
2. Russia had it easy in 1908, as that comet or asteroid hit a very sparsely populated and remote location
3. and where the hell are YOU from, if not from Earth? That sentence alone raises "nut-job" red flags
"It amazes me how many people think they are so immune to the highly controversial threat of comet/asteroid strikes."
1. Such strikes are not controversial. they simply ARE, and the threat of more of them simply IS. what we should do in preparation for such a strike... now THAT is a matter of some contention.
2. Only morons think they are "immune" to this threat. We are not morons.
"The reason for the post is obvious. I don’t have to justify my concerns about this topic, and being labelled a troll for it is just ridiculous."
1. No, they aren't
2. Yes, you do
3. No, it isn't
Ball's in your court, Bucko.
