OK, I understand people's issues with it and have listened to people go into much more comprehensive attacks on the idea, but I think it's devil's advocate time.
1) religious texts warn of the dangers of a NWO/one world government and how it will be headed by the anti-christ/dajjal - irrelevant.
2) why there is a need for one government to rule the entire planet - it would certainly lead to an end to conflict over commodities.
3) will said NWO be working for the interests of the people or the interests of big business? - you'd hope in the interests of humanity.
4) a one world government will limit/stop growth of developing/third world countries to maintain the status quo - or perhaps equalise monetary assets and make the world a fairer place to live without capitalisation favouring the 'already-haves' over the 'have-nots'.
5) it'll be full of white men in black suits. - irrational. The Chinese would have to be a huge part of it since they have such a huge slice of the population. Same with India.
Don't get me wrong here, I'm not saying it's an idea without risk and that it's definitely the way humanity should be heading, but I believe in thinking things through and making your own decisions based on your own opinions, not those of others who have a soapbox to stand on
