But eating meat isn't immoral. Regardless of the fact that personally killing animals is unpleasant. I'm not really feeling you on this one lemur, though I've heard people say this before. The argument seems to be tangled up somehow. If it was wrong to kill animals, it would be wrong to buy meat at the grocery store. But since it isn't, it isn't. Our willingness to kill them ourselves is irrelevant. A kleptomaniac may be willing to steal but that has no bearing no the morality of theft. I think it's just one of those vegetarian arguments, I saw it on a billboard somewhere once.
I think if I claimed that using a toilet was immoral, and used the argument that you wouldn't be willing to clean a septic tank, it would be a parallel argument. And you would in no way have to prove your moral soundness by actually cleaning a septic tank.
I'm not opposed to personally killing animals (have done so), but I'm not going to go out of my way to, it's unpleasant. And it's a good think that it's unpleasant. That's an important instinct. The most valid argument made by vegetarians is that regularly killing animals hardens people and weakens that instinct. I don't think it's a coincidence that dog fighting and such were more popular in times when people more often killed animals themselves. Grabbing a box in a grocery store doesn't weaken that instinct.
-edit-
Wow, that ended up long and rambling. Anyway, in summary, I think vegetarianism and animal rights is a complex debate, and that the pro-eating them argument is not helped in the slightest by a willingness to kill the animals by hand. If someone said they didn't think stealing was immoral and I disagreed, I would not be impressed by their willingness to rob a gas station even if they are now less of a know-nothing.
