hree mothers of gay men joined hundreds of others in the Capitol on Thursday with one goal. “It’s important that they be treated equally,” Mabel Galvin said. Government should treat all citizens the same, added Kay Allen. And Therese Presley said government discrimination against gays fosters “divisiveness within families.” The three Duluth women stood among what organizers said was a crowd of up to 2,000 in the Capitol, all asking state leaders to legalize gay marriage. It was one of the largest under the Capitol dome in the past few years. The Valentine’s Day gathering brought gay couples, parents and other supporters together as legislators consider whether to overturn a state law banning same-sex marriages. No bills have been introduced, but they are expected to be filed next week. The three mothers thought about their sons during the rally.
