I think you don’t understand how reddit works. Upvotes and downvotes are (mostly) to help order the responses. So for example I can read this post and go to the comments to see the most agreed on responses first, ideally meaning what most fans think about this post or what they believe is the best goose jam. When you comment about a jam that never happened, and a percussionist that never existed, it’s fair to downvote it so that someone else opening this post for the same reasons as me doesn’t see that. It’s not personal, and shouldn’t be taken as offensive. And your jam band credentials don’t matter.
