I don't know how you could get that impression given the existence of lemmy.ml, lemmygrad, and hexbear.
.world, which last time I checked has more or a similar number of registered and active users than all of those combined ABSOLUTELY love him. You can't say even the most innocuous and well-documented things critical of him in its communities without being downloaded to hell.
Even !workreform@lemmy.world will bristle at the mention of him violating the rights of the rail workers to strike for a better deal, forcing them to take the crap deal corporations offered.
On kbin it is displaying 1 upvote, 1 downvote. It seems lemmy has a tendency to miss some comments/votes. I appologize for not considering that first.
Still, the votes on this post are a poor test of Biden's approval/disapproval. Instead you should look at the actual polling. I think if you were to actually ask the 8 downvoters, they have done so because this post is just silly. Because again, nobody likes Biden to begin with.
Don't know about senile and definitely not a fascist but yeah, he's on the more conservative end of neoliberalisn (a center right to right wing ideology) which by definition makes him right wing.
