Well then, I guess you must be from another nation. Liberalism has nothing to do with hippies. That's something different. That was a direct opposition to the lies selfish men spun.
You 'll notice a big shift after Kennedy was assassinated. It all became there. The country was highjacked in a coup d'etat and NOTHING has been the same since.
If you want to blame the ruin of a country on someone, look no further than the paranoic views of a radical right.
