My objection is not religious based. It is based upon the Declaration of Independence and one of the founding principles of this nation.
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
I'm not just pro-life, I'm also pro-liberty, and pro-pursuit of happiness, for the same reason. I value the other two founding principles equally.
In my opinion, if you are anti-life, anti-liberty, and anti-pursuit of happiness, like the Democratic Party has been and continues to be, then you are anti-American.
