It’s also a nascent movement so it’s not surprising that many people don’t understand it. There are many successful policies that began with very low public support.

Yeah but the policy proposals spelled out earn actual majority support in polls, instead of tiny-minority support. It's a terrible self-defeating name/slogan.

I'm sorry but I find this kind of nitpicking in bad form. People are going out and taking action to bring attention to a problem in what is obviously the best way they can do so. If you have an idea about improving marketing, why not spend that energy helping/proposing something and volunteering?

Aside from that, I think there is more to consider than just what will appeal to public opinion; dry attempts to shift one’s words to match opinion polls is how many politicians lose elections by coming off as pandering. There is a sense of urgency and emotion in the original phrase that might be important in the broader picture and in the long term.
