Most skeptics (sceptics is the proper spelling

) are fairly reasonable people; it kind of goes with the territory. As the person making the claim, it is upon the claim-maker to provide positive evidence for the claim.
The way I see it, there are always two (or more) sides to any issue, if there weren't more than one side, there wouldn't be an issue, right?
In a formal debate, both sides present their case and then question and/or respond to one another via a moderator. Is it possible to have such a formalized debate if only one of the people is making a positive claim while the other is just skeptical of the other person's position?
It would be like Obama and Mitt having a debate where Obama is making the positive claim that his healthcare bill should go through while Mitt is just bashing the bill. But Mitt isn't providing any alternative positive claim, he's just skeptical of Obama's bill. Is this even a valuable discussion to have? Mitt isn't actually bringing anything to the table. Would you vote for him if he never brought anything to the table for the whole campaign but only pointed out what's wrong with Obama ideas via his skepticism?
This is what I see on this forum all the time. The atheist never brings anything to the table because every time they are questioned they automatically throw up their fences and say, "No, no, no, I don't have to back up my position, the burden of proof is on YOU." Okay...so you're not bringing anything to the table, you're just asking questions after questions that aren't going anywhere. Atheists have set up a situation where they can never "lose" a debate because they haven't actually said anything...they've just asked questions. Mitt can't "lose" his debate with Obama if he never makes a positive truth claim because there's nothing to lose! Its the cheaters way out of a debate, and I don't think it would even be allowed in a formalized debate, yet it happens here all the time.
There are two (or more) sides to any discussion. There is theism and then there is atheism (with a bunch of others as well). If we, for simplicity sake, say there are two sides, atheism and theism,
then is there any way for the atheist to make a positive truth claim that they actually have to back up?
I guess you could say that you could prove your position by proving the alternative to be false. That's a legitimate tool used in logic and mathematics. But I feel like it doesn't work in the situation with Mitt (in politics) or with atheists (in philosophical debates) because there isn't one definite alternative, there are hundreds of other alternatives that you would have to prove false. Even if Mitt knocks down Obama's one vision for healthcare in America, there are still an infinite number of other options to be knocked down. Similarly, even if the atheist convincingly knocks down the specific Christian concept of God there are still thousands of other God concepts, plus hundreds of other views of God/gods/deism/pantheism etc.
I guess you could also say that, "Well, I'm not trying to prove anything, I'm just unconvinced." I've never bought that response from an atheist. The atheists I've encountered live, act and talk as if there is no God, and as if that's the
truth. They are not like researchers, constantly looking for evidence for God everywhere they go. They are not spiritual seekers, seeking everywhere they go. They are not "on the fence" on the issue, they are clearly in the "atheist" camp and they will debate theists passionately; more passionately than someone who was "unconvinced" should. An unconvinced person should sit back and listen to the discussion between two people and attempt to make their decision after that. The unconvinced person is not the one passionately in the fray. The unconvinced voter doesn't run for president; if all Mitt did was question Obama, then he could not turn around and say, "Oh, I'm just unconvinced of his position." Then why are you running? Why are you so passionately involved in disagreeing with him? If you so passionately disagree with him then you must have a position that you hold that is of
more value than his position. Is atheism more valuable than theism?
**Note: all my examples using Mitt and Obama are just that: hypothetical examples. I don't want this to turn into a political debate.
