I volunteer my time to several things I think makes a difference. Helping illiterate homeless and poor people learn how to read is one. That way they can read the Constitution themselves and learn how laws are made and which politician is saying and doing what.

Reading is extraordinarily important in learning things such as what a peraon's civil rights are.

Suggesting ways people can help make a difference if they really care about the issue isn't really "telling everyone else what to do".
