The only place where a polite discussion about kittens can lead to a flame war about government conspiracies.

There are 4 types of YouTube comments:

1. Short, 1 to 3 syllable comments. These are usually positive, but are still retarded.

2. Advertisements of any kind. Usually for crappy porn sites, or for other YouTube channels.

3. Negative criticism. While this isn't usually a bad thing, the highest level of criticism on YouTube consists of insulting someone else's sexuality

4. The insane, rambling argument. These are most common on religious and political videos, and always against the ideologies espoused in the video. Often it starts out somewhat sane, but quickly declines into runon sentences about government mandated brain control.

When read, reader usually dies a little inside.

In theory: A section of the video hosting website 'Youtube' where people may comment on and rate videos uploaded by users.

In reality: A complete annex of reality where factual accuracy, literacy, mutual respect and general good will are almost completely devoid. The closer a video touches upon religion, national identites and race, the more ludicrous and profane the comments section will be.

Common inhabitants (and often combatants) of this inhospitable environment are:

Zealot the Cleric, Professor Know-it-all, Professor Wiki-it-all, Armchair Activist, Keyboard Patriot, xxxEmoKidxxx, Blatant Illiterate (aka The Child who was Left Behind), Raging Homophobe, Capt. Conspiracy Nut and Sir Lastword of Ihavenojob-shire.

Not has such an uprising of racism, hatred, stupidity, misspellings, and other such reprehensible behaviors been seen since the founding of 4chan in 2003. Allegedly a mini-forum, so to say, to give video watchers a place to criticize, discuss, and comment. What can effectively be called the "comment section" on YouTube is truly devoid of anything redeemable in nature, where commentators seemingly try their damnedest to do anything but comment, criticize, or discuss. Reading YouTube comments on a video relating to politics, religion, stereotypes, and the like, will often compel those curious enough to let their eyes dangle at the mosh pit of insanity to wonder what has driven most of these people to achieve such great failure.

The comment section on YouTube is truly despicable, mainly due to a lack of moderation by the staff, video owners, and etcetera. True, the occasional intelligent person will seemingly slip through the waves of unintelligible jargon that YouTube renders endlessly, but they are often rare, like finding a lonely message in a bottle, floating among the waves in a sea of urine.

Honestly, I'm appalled.
Never in my life have I seen such volatility, such vileness, such venom, such inhumanity until I encountered the YouTube comments section when I first joined YouTube.
Everyone is opinionated to some degree; and for some reason that doesn't apply to the YouTube comments section. Trolls are everywhere. Home of the notorious flame war. Spelling and grammar are raped, beaten, tortured, shot, then hanged. Ranting will only get you hated. Once in a while the intelligent person will spring up, but you have to look for him... or her. But for the most part, it's amazing, almost laughable at how disrespectful we can be and have become.
Be careful what you write in the YouTube comments. I advise you.

The brutal and repeated rape of the English language.
