Yeah, I grew up in an Evangelical culture, even though my family wasn't Evangelical. My best friend was though, so I got a bird's eye view to purity culture.
Two particular meltdowns during my school years stand out. The parents freaked the fuck out over sex ed week in physical education class in 6th grade. Then the same ones had a collective spaz out because the high school mascot was a devil head. Worse, nobody but them wanted to change it which, apparently, was proof positive that Satan was brainwashing the town's youth.
Oh, the irony.
