To be honest, I was a little torn by this one.
I truly believe in what was being said in the petition re: education rights and gender rights. However, the wording of the petition was quite aggressive and emotive without strong data to support it (eg. stats from UN or WHO or...?). Because of that, I'm not sure that it will be particularly palatable by a government office i.e. the Secretary General.
All that being said, it's important enough for me to sign, and it's not like I've never had people misinterpret my good intentions.
