I have shot a few rifles in my much younger days, mostly at gophers that were damaging a relatives cattle pasture. My father did hunt, for food probably before I was born or very young. He never continued the practice. I do have a number of cousins that hunt regularly, but I was never really interested, I am middle of the line when it comes to gun ownership. I understand the need for proper safety, handling and storage of rifles for hunting purposes. I have never really understood the need for hand guns.
I have a brother in law who used to try and one up me in technical knowledge related to electronics and computers. I just never really talked with him much, like you say no point in getting upset. We all have our opinions and an argument is no place to learn and grow our knowledge.
Most arguments just don't seem worth the effort to me these days; maybe an age thing? I just tend to let things go as going to war with people doesn't value-add my life. People will think whatever they will irrespective of what I think or say.
Some people have to be right all the time as it gives them a sense of superiority, validity or relevance; something like that I guess. I'd rather enjoy life a little and let people think whatever they think, right or wrong.
