Well, if it helps, some solar punk posts like this one go mainstream. I think there's only about 150 active solarpunk members so when a post gets close to 1000 votes that means non-community members are voting.

I've commented on solarpunk stuff that was mildly in capatlism defense (much more controversial than your question), and had great conversations/critisims with almost no downvotes. So I think/hope the downvotes are not from the core solarpunk community. It is still sad, but I would be much more sad if it happened and the main post only had 100 upvotes.
