Kluwe and his wife Isabel had their first daughter in July 2008, and their second in 2010. He also wrote a blog named "Out of Bounds," which appeared on the website of the "St. Paul Pioneer Press" until 2012. He quit the column in protest after the paper published an editorial in support of the Minnesota Marriage Amendment which would have amended the state constitution to ban same-sex marriage: Kluwe was not surprised at the paper's position itself, but felt that the editorial was derogatory to amendment opponents while feigning neutrality.
