If I had a nickel for every time somebody told me my Pro-Life stance was invalid because I was a man, I'd be incredibly wealthy. I bet a lot of you are in the same place, yes? However, it's at best a sidestep argument intending to push one's opponent out of the debate. Ultimately it's an issue of requiring an unreasonable level of connection to an issue to even discuss the topic, not to mention a way of validiation of ignoring reasonable objections to maintain one's own position.
Now this isn't the case for all, and frankly most, of the people who use this argument. Actually, the real perpetrators of this argument are those who began to use this defense of abortion. It's not hard to win an argument when you automatically remove half of your opponents from the field, especially when men of the Pro-Abortion ilk are not told their opinion isn't valid. It's an issue of allowing the other side to set the premise of the debate, one we must not allow.
This is so critical, because we must not allow the Pro-Abortion lobby to wipe away the objections of men because of what our objection to abortion is in the first place! Our objection to abortion is that we believe a human being is a human being, whether born or unborn, and that destroying an innocent human being is always murder. Being (hypothetically) the mother of the child vs. the father has absolutely nothing to do with the situation!
Let's imagine we all woke up this morning and opened our favorite online newspaper (or perhaps hard copy newspaper if you're one of the seventeen people who still read the hard copy paper while also still consuming blogs like this one) and read this headline: "Father Smothers 6-year old son with Pillow." Would anyone consider it a valid statement to say to a woman, "You know what? You're not a man so you can't possibly understand why a father would snap like that and kill his child!" Absolutely nobody would accept this argument! Nor should they. It does not require someone to be male or be a father to believe it's reprehensible for a parent to murder their child. Period.
Yet somehow the Pro-Abortion lobby wants us to suspend our own personal outrage at destroying an innocent human being because we don't have a uterus. It's silly. Our issue is protecting a human life. That's the issue. We can have an honest and open debate about it without having to disregard someone's valid opinion because of their gender. It's a false rejection of a position.
Bottom line, if you're going to debate with somebody, don't disregard positions for such frivolity as gender. Especially when the question at hand genuinely ought to be "is that unborn child human," with the logical conclusion being "if the child is human, abortion is wrong, if the child is not human, abortion is fine."
Unfortunately, debate on this premise is not going to help the pro-abortion lobby's position in the least, because the most logical conclusion is, at least for now, fall on the side of caution. It is better to protect something that isn't human than to accidentally destroy something that is human.
