I’ve noticed this with people in the free thought community. They have a sort of skeptical dial that they can ratchet way up when it comes to Christian beliefs so that almost nothing could provide sufficient evidence for these, but when it comes to their own worldview and commitments they dial it way down so that they don’t need to provide virtually any justification for their own beliefs in order for these to be rational. That, of course, is just hypocrisy. That is self-serving. If they are going to extol the virtues of doubt with respect to religious beliefs, they need to also extol those same virtues with regard to their own atheistic beliefs. —William Lane Craig (cited in,  WWJD: How did Jesus deal with skeptics?)
