That would undercut the value of the proposition. The reason why it needs to be required is because it is responding to a defined lack in the young people we're graduating into our society. There is something identifiable and identified missing from their formative process. The only way to fix something that is broken is to fix it, not think about fixing it and then turning around and applying incomplete measures instead.I could agree with that as long as it wasn't a required course.
Beyond that, you didn't provide any substantive explanation why you feel that young people and society wouldn't benefit from a civics requirement for graduation. What is the harm that comes from our society expressing to its youth reasonable expectations for contribution to and participation in society?
Or is your objection solely that some students would be "allowed to" satisfy that requirement through community service instead of the in-classroom civics course - that you object to any students having that more hand-on, experiential opportunity to learn, and rather, instead, all students should be forced to gain that understanding through the classroom experience?
