He is saying the slip of "the innocents" vs. we us is an easy slip to make. Not your slip.
This also wasn't my entire reasoning for jumping on 2015. I also mention that Colorado voted and accused 2015 of mafia day 1. My theory says they saw that and decided to "infect" Colorado not realizing that this would kill him. Normally you don't kill people who voted for you because it makes you look guilty, but they weren't trying to kill him and we wouldn't know about the infection.
Ah gotcha. Thanks for the clarification.
