American conservative outrage at Grammy gay weddings US conservative and Christian groups have reacted furiously to a mass wedding, which saw 33 couples - straight and gay - legally hitched before millions of TV viewers as Madonna performed at the 2014 Grammy Awards this weekend. Quadruple-winners Macklemore and Ryan Lewis accompanied the nuptials with a marriage-equality anthem called 'Same Love," before Madonna, wearing a white suit and cowboy hat, entered to perform 'Open Your Heart" beneath an ornate mock-ecclesiastical set. Amid thunderous applause, Macklemore used his hip hop lyrics to attack opponents of gay marriage. "The right-wing conservatives think it's a decision, and you can be cured with some treatment and religion," he sang onstage at Los Angeles" Staples Center. The issue of same-sex marriage has divided America; it is allowed in 17 states, while banned in the remaining 33 states. Some conservatives turned to Twitter to voice their anger. "What do you expect from this crowd of the Hollywood elite?" said Steve Scheffler of the Iowa Christian Alliance. They are certainly out of the mainstream of American thinking and what this country was founded upon. It is sad that they talk of marriage equity, who knows where that will lead to. It is a crowd of people sitting in a closed room knowing nothing about what is right and wrong. Tim Graham of the Media Research Centre, a Conservative group based in Reston, Virginia added: They can say this is not a stunt, but that's exactly what it is, a piece of musical agitprop to mock the traditional values of conservative American Christians, Jews, Muslims, and others.
