Matt Dillahunty's things that he would call "sins"

Starting around 3 min.45 sec.

1) Credulity
2) Voluntary wilful ignorance
3) Letting fear prevent you from understanding reality
4) Limiting the rights and freedoms of others in order to make them abide by your standards.
5) Sacrificing the mental, emotional and physical well-being of a child in deference to your religion
6) Wasting the one and only life that you know you are going to have worrying about and working for an afterlife that someone told you might be there
