How about just don't open your ******* door? With current CHL laws, if you have a CHL, they could still try to nail you on your own property for being in possession while intoxicated, if they wanted to. You might be able to beat it in court, but you'd have to have a good lawyer. And if the licensed OC bill passes, it'd be the same scenario.
No, I don't care that much about beer that I'll refuse the closest thing to constitutional carry that we can muster just so I can keep my handgun on my hip while I get hammered. If you're that worried about it, just carry something other than a handgun when you drink - which probably isn't a good idea anyway, regardless of the legalities.
