Why keep repeating your position that it is best to say nothing? Be a good friend to the pro-life FR members and say nothing more...
Because I lost a child and I network every day with mothers who have lost children and I often do my best to heal their faith in God that has been damaged by clueless moralists.
And I feel a strong need to spread the word and tell the OP to butt out. Presuming he is a best friend.
Now, if you have selected clothes for your child to wear in his coffin and put a toy in his hands before they closed the lid, and then laid on the dirt over his grave the night of burial to keep the rain off....then we can talk some more.
