More importantly, you hurt the poor in this world
I think the problem is rather that we could be hurting the rich in this world. Which is why they paid for propagandists to spread disinformation that you fell for, and now spread for free.
And as far as credentials go, would you want me to lie about that? I just try to be as transparent as possible, explain why I think something, and then let people decided for themselves what they think of that. Besides, it's more about what we achieve as a collective of idoits than about me and my credentials, and I think so far we did pretty well describing what has been going on in the Arctic in the past 4 years.
