I'm sorry Beckett. :(
There are a LOT of people who don't even believe he is real, or who truly do feel he is a joke. And we can't do anything about what other people believe. I know it is angering ,frustrating, and insulting. It's nearly impossible to avoid running across these types of memes and comments when they are out there.
I would hate it if you left this site, though I do understand your feelings on this. Maybe we will get our wish of being able to block undesirables in the future. I am sure that would go a long way in removing most of that. But don't make any decisions in haste or out of anger. You may regret it later when you wish you would have paused.
Love and hugs
