Yes, infiltrations do happen all the time, but it was Randall Terry and Alan Keyes pushing the baby carriages. If they are infiltrators, they’ve been fooling people for a long time. I did say “in this context.”
The article states only that they were among others who pushed carriages with dolls covered in fake blood. That's bad enough in itself. Anyone with an iota of good sense, and taste, would not be among these crackpots, "infiltrators" or not.
Randall Terry does nothing positive for the pro-life campaign, rather he's an abject embarrassment. Keyes should know better, obviously he does not.
I don't see where it says Terry or Keyes were actually pushing carriages. Can you show me where it says that?
