How about when they teach your grandchildren in Kindergarten that Heather has 2 mommies and the teacher reads "King and King" to them in class about 2 princes marrying? You would be OK with that. They have been doing that already.
What will you tell grandchildren when they see the vulgar gay scenes on TV? How will you explain that to your pre-K child or grandchild. This is our wickedness what they did today.
