There's a whopping community of skeptics, atheists, and people that are just plain practical. While many of them may not agree with each other, there's a lot to learn from these channels. I've put together a list of some of the channels that I enjoy and find relevant.
I've considered making my own channel, but I just feel like I'd be putting a lot of effort into something that not many people would bother watching. Plus, my only webcam is very old and very crappy.
Nonetheless, here are some wonderful YouTube channels that I subscribe to, with quick descriptions. This is far from a complete list, so I will drop some more in later blogs.
Probably among the most popular in the YouTube atheist community, Thunderf00t is a bonafide scientist with an apparent contempt for stupidity. He's most known for his series, Why Do People Laugh at Creationists. While many of the videos in this series are a response to the incredible claims of another YouTuber and creationist VenomfangX, it provides material for solid rebuttals and debunkings of incredible claims. Thunderf00t has gone head-to-head with the infamous banana man himself, Ray Comfort at least twice in person, and has even paid the hateful territory of the Westboro Baptist Church a visit. "TF" is also a regular host of the Magic Sandwich Show, along side other prominent YouTubers, AronRa and dprjones.
Don't let the scary, long-haired, biker dude in the videos scare you -- he's one of the smartest and wittiest people on the planet. As a parent of a Texas middle-school student, AronRa is one of my heroes. He's attended panels with the Texas Board of Education on numerous occasions to fight the encroachment of creationism and other religious beliefs on our public school system. AronRa has an extensive knowledge of biology, including the demonized Theory of Evolution. I've probably learned more from him about biology than I have in school. I've attached the first in his most notorious series, The Foundational Falsehoods of Creationism.
On the lighter side of things, DarkMatter2525's usual content consists of hilarious animations, often laced with profanity, basically bringing the absurdity of religious claims to light. Kick back and enjoy the exploits of Yahweh and his sidekick, Jeffrey as they try to create and manage the universe, or enjoy this one below which will introduce you to a slew of additional prominent YouTube atheists.
One of the funniest channels belongs to NonStampCollector, so named because of his hobby of not collecting stamps, in comparison to his religion of atheism. The sharp, rapid-fire wittiness, and bladder-shrinking humor make you overlook the crudely-drawn slideshow animations. NonStamp is notorious for using the bible to fight the bible. If you want endless examples of biblical contradiction that you can barely read through your tears of laughter, this channel is a must.
A.k.a. the Bible Skeptic, Brett is well versed in both the bible and reality. The Bible Skeptic has video series' debunking anything from the ethics of God sending bears to maul taunting children to the existence of the nephilim (evil giants in the bible). These videos are split in to 10-30 minute segments for easy watching.
