The gesture, which children use when singing “like a diamond in the sky”, is similar to “vagina” in sign language.
Parents at the Sure Start mother and toddler group in Acomb, North Yorks, slammed the move.
One said: “These are innocent children. Now every parent may worry their child is making an offensive gesture.”
But a spokeswoman for City of York Council — which is responsible for the group — insisted it was “a sensible decision to stop deaf children or parents being offended”.
A spokesman for the Campaign Against Political Correctness said: “This is ridiculous. Perhaps it is time for the adults to grow up.”
Seriously though?? SMH…ok
