Chuck:
Grace that is imparted in baptism may be rejected. It is a gift that can be refused.
The baptism hang-up by protestants is the contextual problem they have with other areas of the faith. And the baptism controversy is typically used in a derogratory way to undermine the Church.
Remember, every protestant must become their own expert interpreter of the Bible. They wobble around most issues of faith until they put their trust in the Church to guide understanding.
I was born/rasied in a Lutheran church. They baptized infants, as do many other protestant churches. Some do not, but still christen or dedicate, which is using the exact same format, but using the word ‘dedicate’ instead of ‘baptize’.
The general thought is that one should be baptized after confession, much in the same way that priests would wash their hands and feet in the bronze laver, after a sacrifice at the bronze altar for repentance, symbolizing the cleansing. First confession, then a physical/public representation. John’s baptism is no different. ‘Repent’ and then ‘be baptized’ for repentance.
Many protestant view baptism found in such passages as Acts 2:38 to not equate Johns baptism by water, but Jesus baptism of Spirit when Spirit gives birth to spirit, and we are born again. (John 3, 1 Peter 1)
I cannot speak for all ‘protestants’ however, I can asure you that while there may be a difference in understanding, there is nothing derogatory in my heart towards you.
Also, your last paragraph leaves much to be desired. I will presume that the generalizations you made are not absolute in your heart.
