"Third, I would NEVER allow an inanimate object determine the course of a friendship(s.)"
This is all well and good if you are prepared to let other people dictate most of the specifics of your life. I agree with the concept that People are more important than things. Unfortunately, this is not simply about things. It is about family history, political beliefs, life-long hobbies and passions, deep-seated beliefs about personal responsibility, self defense and personal freedom. I also believe that true respect and influence is earned, not demanded.
I afford everyone a reasonable measure of respect just for being human. That is based on who I want to be, not who they are. I reserve deep respect (that allows someone to have significant sway in my life) for those individuals that earn it thru their actions and lifestyle. I have many friendships in various stages of development and depth. Only a handful of these "friends" have earned the privilege to speak into my life and expect me to listen. I hope I have earned that privilege with them, as well, but I would never demand such influence or power.
I guess what bothered me the most about the two instances I mentioned in the original post is that the individuals involved were so dogmatic about the evil of firearms, and by association the evil of those who use them, that discussion was not even an option. I don't usually use terms like "liberal" and "conservative", but in both cases the individuals involved were outspokenly self-avowed liberals. I had listened to them speak about the evils of "intolerance and closed-mindedness" as related to things like sexual preference and alternative lifestyles, but apparently intolerance and closed-mindedness are okay as related to recreational preferences and hunting/fishing/shooting lifestyles.
I have beliefs and convictions regarding ethics, morals, politics, ...etc, but I don't believe I have the right to bully or belittle those who don't share my convictions. Sadly, these "liberals" turned out to be the least tolerant, most bigoted bunch I have ever encountered (qualities they adamantly condemn in others). If they want to be that dogmatic, it's none of my business, as long as they don't insist on enforcing that dogma on me and mine. The level of hostility and intensity they expressed was frightening in both cases, and there is not way in hell I would let someone like that have any influence on my life and what I choose to do or own. I actually felt ashamed, for a little while, of shooting and owning guns. Then I realized my actions and behavior was not wrong in any way. In fact, it was the other way around, and they should be ashamed of their ignorance, intolerance, and intrusion into aspects of someone else's life that are none of their business.
I have found the firearms community to be predominantly respectful, courteous, friendly, tolerant, kind, and generous. I am proud to be a member of that community, and hope to attain to the character of those who were instrumental in establishing, fighting to maintain, and exemplifying patriotism, honor, personal responsibility, loyalty courtesy and self-sacrifice. When someone asks me to abandon all of that for the "privilege" of being their friend, the answer is pretty clear cut.
