Tennessee Senate Bill 632 would strike down local legal protections from discrimination for LGBT Tennesseans, and would make it impossible to pass such protections in the future.  It recently passed the Senate State and Local Government Committee by a vote of 6-3, and is expected to be voted on by the full Senate soon. It sailed through the House of Representatives (as HB 600) last month by a vote of 73-24. What's that smell? I think it's the Constitution burning.
