Now answer the question: Are you in favor of the "right" to carry firearms into a bar? Do you favor the mixture of guns and liquor? I'll bet the questions are not answered.
1.) No.
2.) No.
You lose your bet.
I'll give you an answer; unequivocally, YES!
There is no presumption that visiting a bar makes one less able to responsibly carry a firearm.
Are you in favor of outlawing the driving of a car to or from a bar?
How about liquor stores? How about restaurants that serve liquor?
Are you also in favor of the infringement of the right to carry within a 1000 feet of a school? Do you presume that no one would ever approach a school with a firearm unless they intended to murder children?
I presume you see no "slippery slope". Just how far down have you slid?
