In a Publius Essay I wrote back in 1999, I predicted that by 2007 it would be perceived as patriotic for Americans to smoke American weed and contribute to the tax base. I was off by 7 years.
I fail to see where in this article it backs your prediction. Patriotic was not given as an reason as far as I could tell.
The way things are going, my prediction is that the stars and stripes of the American flag will be replaced by marijuana leaves and anuses. To more accurately symbolize the paramount, defining issues of our modern American society in all all its worthless, pathetic glory... dope and faggotry.
