I remember when the way to get people to "wake up" on creationism was to unite sub-groups and pump out loads of content that rationally went over all the scientific evidence against it and trusted people to make up their own minds, including all of the debates between atheists/anti-creationism and pro-creationism speakers.
Despite there being very little hope in rattling an entrenched belief like that, many people began to think outside scope of their religion and creationism is not as widely accepted as it once was.
I hope that in the future the new generation of rational believers on climate change can adopt a similar non-violent mindset instead of letting their passion get the best of them.
