Daniel Foster at NRO nails it:

Look, the beauty of free speech is that, if you’re inclined to do so, you can write a check to PP in an act of solidarity, or write a check to Komen as an expression of moral approval. That’s all fine. But there’s something quite a bit different, something creepy and not a little despicable, about the Planned Parenthood set’s besmirching Komen’s good name across a thousand platforms for having the audacity to stop giving them free money. And I don’t care why that decision was made, frankly.

Imagine I volunteered to run a cub scout troop, and for years, when the annual soapbox derby came near, I knew I could count on Joe’s Deli as good for a hundred dollar donation. If one year Old Man Joe decided he didn’t want to donate any more — because he didn’t like the design of our racer, or because he thought his hundred bucks was better spent on a little league team, or because he disapproved of the scouts’ stance on gays — what on earth would justify me going on public access TV to grill Old Man Joe on why he hates kids? What would justify me hacking the Joe’s Deli web site or maliciously editing Old Man Joe’sWikipedia page? What would justify me goading a handful of my city councilman into standing up at the next town meeting and publicly calling on Old Man Joe to reinstate his donation?

Nothing, says Daniel Foster, would justify that. And he’s right, because his is the decent position to take.
