Liberal thinking people, such as Democratic supporters in America, (and in Canada, supporters of every party but the Conservatives) make excellent artists, musicians, live performers, and writers. They also have many obvious skills in business, from marketing to engineering. In fact, if you add them up, there are literally thousands of things liberal thinkers do extremely well.
Politics, however, is NOT one of them. And neither is public safety.
Liberal thinkers want to help and Save Something, Anything, Now! Often this means Every Single Person on earth. Often you find liberals who go further and equate humans with worms, and then it includes Every Creature We Know. It's their nature.
Unfortunately, liberal thinkers who get into politics also love government. BIG government and BIG taxes. They see it as their big chance to save the world with other peoples' money. Liberals live to govern; they see it as their calling. They spend their lives trying to convince us that we desperately need them to save us from every financial and personal risk that might ever happen.
Unfortunately when it comes to security they would rather impose more and more restrictions on their own people than truly fight the problem.
Political liberal thinking can be boiled down to a few words: "Just a few more taxes, nude body scanners and breast groping and we'll cure everything and protect everyone!" Sadly, most of the spending any government does is misdirected, wasted, or skimmed by the bureaucracy, lawyers, and the like. Most liberal government security dollars are wasted further on restricting innocent citizens' lives rather than on criminals and terrorists. They'd rather fondle our breasts and balls than focus on the real security threat, which is basically any Muslim. We have a lot less to show for our freedoms, economic health and personal security when liberals are doing the spending. It's their nature.
Liberals simply love to harness up wealth producers like horses to carry them and their grand plans along. They support ever expanding welfare schemes regardless of the taxpayers plight, because only they care. Plus, they OWN the rights to compassion®.
