Here is someone who makes a good point whether you agree with her, or not.  She is willing to stand up.  She wants to "talk"! She wants others to stand up for what they believe in.  As Alice Hoffman said:  "Once you know something, you can't unknow it.  It's an amazing burden that we all share."  We are all activists.  Some of us are activists to keep thing the same, to ignore what is going on around us, by doing nothing.  Others are activists for change they would like to see by actively participating.  It's not the most important thing that active activists have time, or not, but almost all have the "heart".
