Help me de-polarize the world!

I love the idea!!

• Is the mission clear?
  I think you are trying to facilitate better discussions and understanding of different points of view.

• When it goes live will you use it? If so, why? If not, even more why?
  The biggest, well, in my opinion, barrier for these kinds of is that people have limited time for things that don't give them comfort, e.g. an opposing point of view. They lean towards confirmation bias. In a world where you have to juggle a day job, family, side project(s), people don't have time to understand things that they don't already agree with, at least, to some extent. Even when people are invested in something, e.g. reversing climate change, they only pay attention to the things they already agree with, e.g. reducing fossil fuel use in transportation. If you tell them, according to research, moving to a wholly plant-based diet has a bigger impact than choice of transportation (ICE vs EV), it somehow doesn't compute with them.
  I still signed up because I'd be interested in learning more about how you plan to approach this problem.

• What do you think of the videos?
  The guy with the raspy/old voice is no good. You need someone who sounds clear and oozes optimism (sort of like the girl in the flower video). Speaking of the flower video, it made me chuckle since the video didn't seem to have anything to do with your 'product.' All I got was this girl is starting a flower shop even though she's allergic to pollen. :)

Some other feedback you didn't ask for :) :
I would push the video to the side and move the text "It's time for..." up next to it or push the video down. When I go to a website, my first expectation isn't to watch a video on what it's about and how it works. I like a, to borrow a term from screenwriting, "logline" to know why I shouldn't just click away.

Are you aware of https://www.kialo.com/? Might be worth checking out.

All the best.
