I 100% get the need to get information to people out their that somehow still aren't fully aware of the issues. Im struggling to think how though its been on the national news, on tv, radio and papers (online). Some people just either choose to ignore it or just don't want more aggro in their life. Its asking people to change and change a routine they have likely done for years. People hate change and people hate being asked or told to change.
I personally stopped with me season ticket about 5 years ago. The writing was on the wall then he had gone shoz or bust. It was also getting pretty expensive for me. So for me it's easy to not go to games as for last few years I picked and chose. Not this year though.
Biggest problem is that people online are like people driving. People call each other out, argue, abuse, or refuse to listen because they are in a safe place behind the glass of their car and able to drive off anytime. Same online people can say why they like pretty much then ignore any response they don't like or abuse others for having a.different take. Turn off the laptop or app and get on with their day without properly debating or understanding.
I really don't know how you reach people who are not already aware or get everyone unified. My only humble opinion is that people who want to.be involved make it as easy, safe and impactful as possible. This should make it easier for people to join in and snowball organically. Hopefully week by week it grows to a point it cannot be ignored and more and more people each week will feel more comfortable changing their habbits and understanding. I know time is something we potentially don't have much of but I personally and sadly don't know what else to contribute.
A very long way to say I don't know. Sorry.
