It seems, according to the way things have been going, the general public will be softened through the eyes of children. When gays were being beaten up it didn't matter until it was kids. When trans people crossed the gender lines it was totally taboo, until they saw kids doing it.
Some people commented that it was horrible the mom put her kid out there in public but it seems that's the only way they will ever get that this is not learned behavior but something that is at the core of who we are. It's no different than having a scientific mind, a creative mind, being gregarious or being shy. We see traits in newborns and know this is part of who this child is. This is no different and it's our children that are opening the eyes and minds of the phobic that they refused to open before.
