I dont give a damn who it supports. I was at the pointy end of the money from opiumt. You better bet opium goes to support the taliban. (I mean, otherwise, what where them acres upon acres of opium poppies I walked though for) At the same time, other people, anti taliban people, also grow and sell opium. They use that money to prop up the legitmate goverment, to feed their families, and to make a better life for them selves, without the taliban.
The real lack of morals are the people who do the evil. You are not beheading an 8 year old girl for not wearing a burka when you buy a bag of H, that is Abdul Muhammed Al-bumfuck doing it, and he would do it if you got that bag or not.
and I'll kill them regardless of them having new Russian made AK, or a shitty chinese made AK. Since their skill level and training doesnt seem to change regardless of money, and no matter how much smack you shoot, they aint gonna be buying Su-30MKI's and T-90's
tl;dr people who do evil are evil, and would do it regardless of how they got the money for it.
