It's not just on the internet....it only allows people to hide behind their computer so they are often compelled to say things that they would not dare say to someone's face. Doing such face to face will can result in what we call back this way....a butt whooping.
Morons are everywhere....I see a them all the time....people doing stupid stuff or saying stupid stuff in public.
Having lived in Japan, Canada, England, Germany, Spain, The Middle East, The US among others....let me tell you. Morons and bigotry are not specific to any one country - They exist everywhere.
