I created an Atheist / rational thinker store, mostly out of anger and frustration at the general public's stupidity and/or apathy about just these kinds of things. Check it out if you like... I keep all of the prices as low as is possible through zazzle in order to get as much out there as I can and help spread the word that we’re not going to take this shit anymore. :-)
