Why is it acceptable?

Why would you say that? It's just that most of the conservative Americans doing the talking are the ones still going on and on about how Obama isn't an American citizen, or how he's the Anti-Christ, or secretly converting the US to Islam, or...

How about questioning things he's actually done, as opposed to feeding into pointless conspiracy theories that have already been disproven, repeatedly?

Yes, I know many folks were still (and still are) complaining about Bush "stealing" the election in 2000 and 2004 but the majority of folks had already moved on by this time in Bush's first term.

Times when the Right has been given a chance to speak out, all we hear are the ridiculously fringe rantings from folks like Rush or even Palin. These people don't - and shouldn't - be allowed to speak for the Republicans, unless that is, you really think the Republican party has become nothing but a bunch of rambling radicals whose ideas are equally as ridiculous as those from the rambling radicals from the right.

Well Its because not who is Continuing the mess we are in but Who started this mess in the First Place and Its the previous Administration is why we are in this mess, Hoping the Current one still can get us out of it theirs still Hope.

Double standards.

It's the same reason people were able to question Bush's policies and be praised for it, but if you dare question Obama's policies, people scream "OMG you are is racist!!!" despite the fact his skin colour is not even being brought up.

Liberals are not the brightest bulbs in the box. They use emotion rather than logic and reason.

all politicians moan about the opposition...but i can tell you this...most of the world disliked America's previous government & Mr. Bush.
