Fred Phelps
Fred Phelps was the much-maligned pastor of the cultlike Westboro Baptist Church. Phelps took a hardliner fire-and-brimstone attitude towards society, laser-targeting his efforts on homosexuality. Using cheeky slogans such as "God hates fags" and "fags die, God laughs", he additionally considered anyone with a more benevolent attitude (even if only marginally so) towards the gays than him a "fag enabler" and guaranteed a spot in Hell. Even mainstream anti-gay evangelicals condemned Phelps, albeit for tactical reasons as their viewpoints shared more overlap than the mainstreamers would willingly admit.
On top of his fringe views, the unintentional comedic gold in his sermons (outbursts such as "YOU'RE GONNA EAT YOUR BABIES!") and his church website's tacky ventures into song parody made him a ripe target for Internet mockery in mediums such as YouTube Poops.
