How many times have you been pregnant?
How many times have you sat back and watched someone you impregnated physcially bear all the responsibility of pregnancy?
Most men should agree to one thing, when it comes to pregnancy, their part is all pleasure, no pain by comparison to those impregnated. Yeah, they can whine all they like about caring for a pregnant wife or girlfriend, but they ain't the ones that are pregnant and they don't have to worry about the other half leaving them while they are pregnant, about the guilt trip of considering the thought of terminating a pregnancy because the impregnator found someone else to do the "impregnate and leave" dog and pony show with.
Perhaps you think you know what being pregnant is truly like? So be it.
I'll defer to those who actually get pregnant....by those who seem to think their part in a pregancy is "tough" work that requires facing the same sorts of moral judgments and dilemmas as those they impregnate, if they decide to do anything, but give birth.
Frankly unless it is your personal pregnancy, what you personally believe shouldn't matter any more than whether you believe in aliens. You're entitled to your beliefs but it's not up to you to decide what if anything should be done about it. To those to whom it is a reality it can be an affliction, an illness or a thing of joy.
