The excuse would go like this: "What's the big deal, it's just a little bit of sprinkled water, he won't even know it. And when he is older he can get a real baptism when or if he believes. No need to be so radical and die over it and have the child without a father or a mother. Besides, Romans 13! Hebrew 13!
For those who think this, say this, or do this - shame on you. Shame on you for spitting on all those who were slaughtered over this matter. You think you love Jesus? You think Jesus loves you? You think God is blessing you and answering your prayers? I think you are in a state of delusion and deceiving yourself. You are a disgrace.
