A group called The Child Evangelism Fellowship has established after-school Bible clubs in two Seattle elementary schools, Loyal Heights and Whittier. See this story in the Seattle Times.
I know how this could be a hot-button issue. Believe me, I know. Personally, I'm not a Christian and I'm sensitive to evangelical efforts. That said, I am devoted to fairness and transparency. The same rules should apply to everyone equally - evangelical groups, the military, corporations, whatever. I'm not alone in this view. The U.S. Supreme Court has ruled this way. The District can set some rules. They could, for example, set a rule that any after-school group must be non-discriminatory in their admission policy. That would prohibit the Boy Scouts thanks to their anti-gay policy. It doesn't apply to this group because they welcome participation from non-Christians - that's what the evangelical effort is all about: getting new people to join.
So people could get all worked up over this, but there's no cause for it.
Hey, if you want to start a free-thinkers group, an atheist group or a pagan group, go ahead and you'll get the same opportunity from the District as they have extended to this group. And let's remember that participation is completely by choice. No children are being required to attend. If you don't want your child to go, then don't let them go.
As an activist in the District I sometimes get some flak for having a louder voice than other people, but I'm not taking any opportunities that aren't available to everyone. Likewise this group isn't exploiting any favoritism; an equal opportunity is open to everyone.
