Reacting to a pledge from popular director and “Buffy the Vampire Slayer” creator Joss Whedon to match Planned Parenthood contributions, conservatives responded with a righteous fury calling him a “baby murderer” and saying it was time to burn their copies of “Firefly.”

On the day before Christmas, Planned Parenthood tweeted: “Start your first monthly donation to Planned Parenthood now & Joss Whedon will chip in $50 in your name.” The tweet included a link leading to a page noting Whedon would donate up to $100,000 in $50 increments for each person who signed up to make a monthly contribution to the health organization.

By lending his name to Planned Parenthood. Whedon enraged social conservatives — many of whom accuse Planned Parenthood of murdering babies — and who want the government to stop funding other health services provided by the organization.

They expressed their displeasure on Twitter, attacking the director of “The Avengers” movies, with the first commenter writing, “Thanks for letting me know to avoid the movies of a baby-killing supporter.”

@PPact will not support a group that condones murder of innocents. Also won’t patronize people who support PP.

@PPact I think Joss Whedon is a genius. Didn’t know he was an evil one. Sorry but we’re done. #FormerFan #PPKillsLiveBornBabiesForBrains

Others brought up the since disproved claims that Planned Parenthood sells fetal parts for a profit — the same claim that launched Robert Lewis Dear to attack a Planned Parenthood clinic in Colorado Springs, killing three.

@PPact strapped for cash now that you’ve stopped selling baby parts?

— Angie Burnham (@tobekiwi) December 27, 2015

@PPact Joss is great but I have no interest in helping u kill babies. Are you still selling baby parts to the highest bidder?

— Captain Chaos (@tonyr951) December 28, 2015

.@PPact Which baby part(s) can I get for $100? And can you get Joss Whedon to autograph them?

— Josh Smith (@Ebolamerican) December 25, 2015

.@PPact for a $500 donation Joss Weadon will autograph a 20 week old baby torso just for you!

— I’m a Big Deal (@liberrocky) December 25, 2015

@PPact @instapundit Sell your own body parts.

— Kirk Hawkins (@KirkHawkins1) December 25, 2015

And one person managed to attack a woman’s right to choose while also defending his right to own guns:

@PPact @PPFA Joss Whedon. Gun grabber and advocate of mass murder for fun and profit.
