sometimes I wonder why people post comment like this. I mean does every articles or point of view posted here has to be 100% politically correct, addressed all the little semantic issues and cover all possible counter-arguments? it's called opinion for a reason. people do think out loud. discuss or dissect it. don't belittle it with snark.
