Personally, I would think any logical person would want universal background checks. Wouldn't it make more sense to suggest ways to best make the system work rather than saying it won't work?

Actually I would have no problem if they would make NICS available to the public where a seller could do a name and dob check. But if you start forcing records keeping requirements on non-dealers or other bureaucratic crap, then I would have objections.
Owning a firearm is a right, but selling firearms for profit is not. If a so called 'private seller' is burdened by too much records keeping etc, then he is NOT really Uncle Joe selling some of his collection, now is he? These so-called 'private sellers' are supposed to be making only occasional sales. According to federal law, they cannot be "engaged in the business" of selling firearms. But that's exactly what undercover investigators found. They found private sellers with large inventories doing a brisk business. In fact, one private seller acknowledged selling 348 guns in less than a year.
There are a few people selling any quantities with regularity, the majority of private sales are individuals selling their own guns. Seems like the easiest fix it to change the dealer requirements to gather in the folks operating on the fringes of the law. There is no reason to take a sledge hammer to a problem that a small ball ping could fix. Would that not make more sense?
