It's not an opinion. It's an objective fact: Either he is a sock or he isn't. If you believe he is you need to provide evidence otherwise you're just spouting idiotic baseless accusations just like Birthers. I can say then that you're another JSojourner sock with no backing whatsoever on the same grounds for example.
When they make me a moderator I'll have the tools to provide the evidence. Until then I'm content to spout idiotic baseless accusations, thank you very much.
Oh, and I'm still sticking with overall FF for "Link", regardless.
