I wish I could speak one-on-one to anyone arguing against that whole issue.
The Great Wall of China is one of the wonders of the world, and helped keep intruders out for over a thousand years.
Anyone that can afford it puts up a barrier around their property, whether a fence or treeline.
PEOPLE put up internal barriers to keep people from hurting them.
PLANETS have atmospheric barriers to protect their inhabitants
As long as their are nations, properties, and life, there'll be barriers...it's natural.
The stupidity of opposing what's only natural...well, it's certainly indicative of many positions the first-world-issue brats are having.
I'm not saying this thread has anything to do with that issue, it certainly is likely, but it was not my intent.
This is more about the cost of paint and mankind's suffering graffiti skills.
