One of the things that makes America a great place is the right of the people to peacefully assemble. HOWEVER.... In my personal opinion it is WRONG to recruit a child to protest with you. Regardless of whether or not the protest supports something that would benefit a child, they cannot make up their own mind and make an educated decision about what the protest stands for, so they should not be recruited into protesting at the rally. There were many people who had their children with them which I do not find questionable, but when you hand the kids a picket sign.... that is something I have a problem with!
This is a protest by the Westin Workers in downtown San Diego - they want free medical care for their families. There were probably about 30 people assembled here, but they made more noise than the Occupy protesters did!
