Why should I click an external link (I do not see a link by the way) without knowing where it will send me?
Help with what?
It could just as well be "helping you install malware on my computer".
Tell me why I should click your un-described external link, please?
"I would really like you to click it!" is not much of a motivation.
And no, change.org is not just a nice, non-profit, do-good-only organization.
It has so charmingly been described as:
"Is Change.org just a weapon of censorship?
Has Change.org crossed a line from being a platform to make the world a better place to a tool for the vocal minority can ban things they don't like"
