"Can we sterilize Liberals ?"  

Well, The law was repealed by Dr. Kitzhaber when he was in the Legislature in 1983, but if any of the 'liberals' were:

" feeble-minded, insane, epileptic, habitual criminals, moral degenerates, and sexual perverts, they could get sterilized.  

"Habitual criminals were defined as those who have been convicted three times or more of a felony in any state, while moral degenerates and sexual perverts partly included homosexuals and promiscuous teenage girls."

"Nancy Rae Cook v. State of Oregon (1972), 17-year-old Nancy Rae Cook appealed the Board of Social Protection's ruling that she be sterilized due to mental illness resulting from childhood physical and sexual abuse. The Oregon Court of Appeals upheld the Board of Social Protection's decision, ruling that the state had sufficient interest in the wellbeing of its citizenry to order Cook's sterilization "

One of Oregon's finest progressive movements in its history.
