It's all quite silly to me.
Over time more and more people have moved to the "Wenger Out" point of view.
But those who were there a few years ago haven't stayed where they were. It's not enough for them now to want Wenger out, they always have to get more and more extreme in their views.
Now he's "the worst manager in football", good results are nothing to do with him (although bad results are), they backdate their views and claim he's been failing for 10 years, despite being quite happy for him to sign a new contract a few years ago. And some have even questioned the glory days under him - he inherited a good defence, he got lucky, whatever.

#WengerOut, but let's keep a bit of perspective. I don't think anyone has been overboard in praise for Wenger after Sunday's result.
