We used to settle things with fistfights instead of guns fallacy

I have quite often seen the comment " We used to settle thing s with fistfights instead of guns " comment, usually after a tragic incident such as the shooting death of WAyde Sims. I realize someone is trying to draw a distinction between what they believe is acceptable and not acceptable. Why are there so many times now where only those two options must prevail?

I attended LSU in the seventies and there simply were very few fights, if any such as we have seen over the last 15 to 20 years. Remember the brawl on the parade grounds at a tail gate party a few years ago? There are repeated fights at local college bars and events every weekend. Fortunately, not all end as tragically as Wayde's shooting death. There just seems to be another element now that transcends race, age and sometimes even gender. Sure alcohol plays a part, but there was much partying then and the drinking age was 18 at the time. There simply was not a culture of fighting and shootings were virtually non existent near college communities in that era.

No, I am not looking back at my college days through selective lens. There was conflict, but seldom more than verbal. Whats different over the past quarer century? If you are under 50 you were part of that cultural evolution. What caused it? How can it be reversed to a more civil time
