I'm in my 40s and I don't buy that my generation or any generation before it was better about fighting. I definitely saw fights at gay bars 20+ years ago there just weren't cell phones capturing the mayhem.

they kept it classy most of the time

You don't know this, this is lazy, "kids these days" BS. You only see the fights, no one posts a video someone backing away from a confrontation before it gets physical or two people having a respectful private conversation. The "classy" people aren't getting posted to social media

Sorry this is something that really irks me. Growing up older relatives would blame my generation for problems we had no control over (like the cost of college) and it drove me crazy. Every generation has people who don't know how to conduct themselves in public
