Ideologies suck

What are ideologies good for?
They're just made up reasons to make you mad.
They're just excuses for weakness.
If you can't relax, have some weed. It's good for you. It's medicine for your upset and troubled mind.
If you have enough weed, you don't need no ideologies to feel good about yourself.

Ideologies do cause some changes in the behavior of the state with varying results, monarchies would spend a lot on the clergy, the soviets implemented a few token labor rights.

The ideology of liberty in the US prevented some Generalismo from taking over, declaring himself emperor and causing the kind of hullaballoo seen on and off in Mexico for decades, even if it didn't stop slavery and all those other things liberals enjoy pretending only the US is guilty of.
