Maybe they were afraid of the comparisons with Katniss from The Hunger Games.
I went to the site, signed the petition...and the parent website handling the petition is CHANGE.ORG...who “helpfully” suggested I might like to sign my personal information onto five other petitions...supporting Obamacare, “protecting the children” through new gun laws, demanding “workplace equality” for LGBT peoples, Gay marriage, and some other nonsense. I thought I was going to be able to COMMENT on the other petitions as well, so signed on for one...and was kicked to the next, so God knows what kind of mailing lists I must be on now. Just a warning over who the Brave petition will get you into bed with.
