David at Orcinus has compiled an appendix to his fantastic "Eliminationism in America" series.
It's almost overwhelming, and definitely a handy resource. Take a look.
And before we get into the tiresome "liberals are just as bad!" argument that we've had a thousand times before in comments, please note the names referenced in the Appendix. I'm sure it would be possible to pull an even longer list of people "on the left" saying things that are just as bad by cherrypicking blogs and comment threads, but most of the names listed in David's work are national media figures. It's one thing to make an eliminationist statement in a blog comment thread; it's something else entirely for a well-known media figure to make a similar statement on national television or an equivalent.
Just putting out fires before they start, folks.
