Christian Radio Yelling At Me

[Gawdzilla Sama]

There's a spot on my commute where my local jazz station gets overpowered by an evangelical christian low power FM radio station. I notice it's always shouting men with southern USA accents blathering on about vengeance and wrath. Never hear a female or non-white sounding voice, and it's always yelling at me. 

I find it so off-putting. Does this shouting tactic work with believers? Do people like to feel awful? How does this stuff work?

I have this knob on my radio, turns the sound down.
