Singer Melissa Etheridge has long been a face of gay activism since coming out in 1993. Etheridge has twins with her ex Tammy Lynn Michaels, who she planned on marrying five months after California overturned the states ban on same-sex marriage. Proposition 8 passed in 2008 however, which Etheridge strongly opposed and in an act of civil disobedience, announced she would not be paying her taxes.
