This conversation only happened because someone who already agrees with the topic posted to a site where the majority already agree with the topic. That’s the only reason we’re discussing it. An open letter only scratches the backs of supporters, and nothing else. It’s worthless.
Real change happens on the streets with protests (think Civil Rights movement, Vietnam protests, etc) and with lobbyists on Capitol Hill. It doesn’t happen with open letters, social media posts, or emails to reps.
