Cectic is a webcomic that is over a few years ago (although the author made two new comics recently) whose theme is, as the name suggests, the skepticism. All with some humor, of course.
Some of my favorites:
Failure Prayer - something like that family physicians and patients to make them, to open his eyes a little.
The Tides of Crime - A perfect example of the fallacy is usually described as "counting the hits and ignoring the misses." Obviously the full moon makes no difference, but this does not prevent the police in question to believe it does ... because they unconsciously ignore all the times that his theory is contradicted.
The day Mom found religion - is much easier (and cowardly) to invent "boogeymen" than actually teach morality and ethics to children. When they are mature enough for Father Christmas, it's time to incorporate a slightly less childish ... and much more nefarious.
Aspirin Versus Prayer - When all the results are interpreted according to a distorted view of reality, all these results seem to confirm this view. In the latter case, there is always "God has a plan."
Conclusive Proof - Have you heard of "double standards"? Here is an example of them. For who is so irrational and intellectually dishonest that their beliefs are in accordance with their wishes and not with your observation, it costs nothing to be incredibly "skeptic" for something that does not want to believe, and simultaneously serve as It is the largest of the credulous about something that you want.
An Atheist's Endearment - Occasionally, this comic can be "moving", this is an example. The idea that our lives, our relationships and our feelings are insignificant just because our lives are finite is absolutely disgusting and insulting everything that has ever felt, and we did.
Vocations - And occasionally it is "poetic." The universe we live in is wonderful - but reducing everything to "foideus" or "diznabíblia" is the more limited - and stupid and a waste of oxygen - you can imagine.
Sense of Mystery - a good answer for those who are so blind and ignorant who thinks there must be the "paranormal" to be fascinating universe. He thinks of such barbarity who does not know anything about anything. Bonus for including a scene of the last episode of Star Trek: The Next Generation ("All Good Things ...").
