Not necessarily. Some Freepers seem to be genuine nutcases, and some are almost certainly liberal trolls. I'm sure that your mention of Obama as the antichrist has made their beady little eyes glow.
You might as well ignore them.
Yep. That would be SOP.
There's always been an unhinged FRaction here, but I've never taken them seriously, and I don't know any serious-minded FReeper who does.
I do agree with tyke to the extent that such BS that they're spouting could gain traction somewhere, not for its truth, but just for its existence, and it's pointed out by Obama (similar to the way he bitch-slapped Hillary in the debate with the "silly season" remark) that here is the same tired BS politics as usual . . . talk about playing right into his "change" hands.
