Well I would take it quite seriously, but the sad thing is that I don't think that should be the focal point of any "threat" discussion. Why? Because right at this moment, people are dying in wars, starving to death, suffering immense damage from the current economic crisis, and meanwhile all the kids (both physically and mentally) are living in their Anime world behind computer screens, talking about nonsense that could "ruin" the world.
No, I'm not saying that you are a child in any way (probably because I don't know you at all and have no right to say that) and I'm only answering on why no one really should be taking anything serious in OT. God forbid we start talking about the politics, economics or history - I would get cancer during the first hour of it.
