Exactly. I said the same thing about Palin using her children at every campaign stop. "They are children. They should NOT be on the stage." If a politician uses them for a prop then they can be criticized.
You don't really think an eleven year old is dressed in two different peace sign shirts without urging/permission from her parents, do you?
Having children standing and waving is as old as politics. There are times when a politician “uses” his children (like Jimmy Carter bringing up Amy Carter’s thoughts about Nuclear disarmament), but nothing that Sarah Palin or Barack Obama has done has made them part of the fight.
Having children stand and wave is not too much, and we should be leaving children out of it. Jim may not ban you, society may not shun you, but Jesus loves children and if we bring harm upon them... well, he had a fairly eye opening idea for those that harm children.
So you may get away with it in this world, but may God’s mercy extend far in the next world if children are targets for you.
