This time, though, a battle once waged by far-right red baiters is being led by independents and activists on the left.

“We are not lab rats and reject any attempt to be treated as such,” actor and liberal political activist Martin Sheen and his wife wrote in a letter to The Malibu Times last month after reading about MWD’s fluoridation effort in their latest water bill.
