RationalWiki's 2018 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff — we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone seeing this today donates $5, we will meet our goal for 2018.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

Donations so far: $3383Goal: $5000

Greydon Square (born Eddie Collins in 1981) is an atheist rapper,[1] Iraq War veteran, and founder of the atheist music collective known as Grand Unified Theory (#GU). His music tends to focus on God (or the lack thereof), Jesus, atheism, support for members of the LGBT community, and other thought-provoking subjects in order to educate people about science, rational thinking and secular humanism.
