[13] In the summer of 2017, Dillahunty joined a speaking tour where he shared the stage with fellow atheists Sam Harris, Richard Dawkins, and Lawrence Krauss.

[17] In October 2011, he married The Atheist Experience colleague and co-host of the Godless Bitches podcast Beth Presswood;[18] the couple divorced in 2018.

[22][23][24] He is one of the subjects of the documentary films My Week in Atheism (2014) by director John Christy,[25][26] and Mission Control Texas (2015).

[33][29] Alongside fellow activists Seth Andrews and Aron Ra, he traveled to Australia in March 2015 as a member of the Unholy Trinity Tour.

[36][37] In 2018, Dillahunty participated in a discussion with Canadian psychology professor Jordan Peterson in which they encountered areas of disagreement about religion, specifically its relationship with values and culture.

[39][40] He touched on the subject again at a lecture at the 2013 American Atheists Convention in Austin: "They say we're immoral, when we're the only ones who understand that morality is derived from empathy, fairness, cooperation, and the physical facts about interacting in this universe.

After hearing that Secular Pro-Life set up a table at the 2012 American Atheists convention, Dillahunty challenged a representative of the organization to a public debate on the issue.

[44] He and Beth Presswood later appeared on Amanda Marcotte's podcast RH Reality Check to explain the events of the preceding years, and said that "the optics of a cis male without a womb" debating women's rights is not what he wanted to advocate, and would let others take the lead in public on the issue.

Dillahunty rhetorically asked, "how popular would psychics be, how popular would ghosts be, if there wasn't this monolithic idea that 70-80% of the population believe, that within each of us is an eternal soul that leaves the body when we're dead and either goes on to some afterlife or lingers around here on the Earth?...If you teach people about what we know, about what most likely happens when we die, they will strive to treat people better while they're alive, and their grief will be lessened because they understand reality."

In an interview published by the Norwegian Humanist Association, he said he does not see why religious claims about reality should be treated any differently by skeptics than conspiracy theories and allegations about alien visitation.

[46] Dillahunty's explanation of the philosophical burden of proof is often illustrated through the 'gumball' analogy, conceived by then co-host Tracie Harris: if a hypothetical jar is filled with an unknown quantity of gumballs, any positive claim regarding there being an odd, or even, number of gumballs has to be logically regarded as highly suspect in the absence of supporting evidence.
