Wow, a cartoonist actually compared guns to Planned Parenthood?
I don't read the print version of my local paper but subscribe to the RSS feeds of the local news and letters to the editor sections. I noticed several letters complaining about a particular cartoon. So I ran a google search and what do I know...
(In fact my paper endorsed Obama for president and generally supports the liberal side of most issues but also publishes people like Charles Krauthammer or Victor Davis Hanson as well. And toons from hacks like Benson. Oh, not to mention that the Washington Post Writers Group employs both Krauthammer and Benson!)
One letter to be published Sunday says:
Planned Parenthood has a long history of supporting women's health and choices, of which only a part is reproductive health. I have no doubt that without Planned Parenthood we would have a much higher abortion rate.
And Monday's LTTE section had two differing views. Decide for yourself which one was more rational.

Surprised this post is still here 
Since that time several others have noted the rw drawing comparisons as well, something I predicted they would do and which I actually understand to some extent (as I am surrounded by rw family members - and no, I am not unfriending my family on FB so I will continue to get this stuff).
There are two mindsets here - one is the rw who sees abortion as something that does not need to happen since people have the choice to not have sex, to use birth control, etc. It is not really a health care choice in that view unless someone is raped (I would say rape and incest but to me incest is just another word for rape).
They see a fertilized egg as life and that life (unlike other lives for some damn reason) should not be taken/destroyed (if we look at the US as a mother and other countries as fertilized eggs though they don't care.....)
On the left side some see guns as killers. Less guns equals less death so ban guns. Both sides want to ban something that comes down to personal choice.
My house, my life, if I want to buy a gun that is my business. Your body, your choice on your medical decisions. Somewhere in the middle people meet up - you can't buy nukes and you can't abort after so many months, etc.
Finding a common ground where all parties can have what they desire seems to be a hard thing to discuss some places. It becomes less about an intellectual discussion and more about religion or feelings and absolutes. And that does not work in a society made up of hundreds of millions of people of varying beliefs/ideals.
