While, as a male, I've casually leaned towards one's right to choose most of my life, it wasn't till about maybe 25 years ago, when the company I worked for at the time assigned me to do security at a women's clinic at about the same time Operation Rescue and it's leader, domestic terrorist Randall Terry, were at their height of protesting, that really put me square in the pro-choice camp.
Witnessing young women go through the most difficult decision of their lives being harassed in the most vile way by those that pretended to have the moral high ground of religion gave me an insight into something that I admit as a man, I would never have to experience directly. For many years afterwards, reproductive rights, bodily autonomy and gender equality, which is all intertwined, become one of the most important political issues to me and I've been a member of Planned Parenthood ever since. That experience, along with several others, is also what gradually drew me away from deism to agnosticism to atheism and admittedly at times, having an automatically hostile response to what I see as the hypocrisy of organized religion.
So I too find it unfortunate that in this instance, the power of money overcame the power of principal and how much of her fake conversion was used by groups and lawmakers as "proof" and justification to suppress choice. It does feel like betrayal, even if given in our sometimes often unprincipled society, it's not unexpected.
