Church members, who recently called TAYLOR SWIFT "the whorish face of doomed America" and promised to picket her Kansas show next month, plan to protest outside 1D’s July 19 concert in Kansas City as well.

According to a statement on their website, “(One Direction are) a perfect representation of [the]sin-chasing, fag-enabling, God-hating, Christ-rejecting UK." And they don’t stop there – the statement goes on: “These freaks and their fans think it’s funny for these five perverts to grab each other’s asses on stage. They glamorize sin and make a mock of God’s standards. Their one purpose is to encourage the youth of this generation to pursue every lust their evil hearts can imagine.” Consider yourself warned about these lads!
