I think Kirk hit the nail on the head. Part of it is attitude. I am a big fan of beer and wine. I drink both and my family has a tradition of homebrewing. However I rarely drink to the level of impairment. If the plan is to become impaired then that plan should not involve guns. If the drinking is more in the order of sipping a glass of wine with dinner or tasting your cousin's latest run of stout then I see no problem.
