While it is unfair to blame modern Democrats for the shortcomings of Southern Democrats in the 1960s, that came well after the end of the Civil War, and it's in living memory for people today. My dad was in his mid-20s when George Wallace won several Democratic primaries.
This is going to bother people like Cotton who are not in the center.
Personally, I like ranked-choice voting. It forces candidates to have widespread support.
It's a wise idea in primaries and general elections, although there is a concern that the results are delayed (On the other hand, I'd rather compromise on the speed with which we get results than on other aspects of elections.)
I think you're responding to points I haven't made.
An increase in violent deaths is a bad thing, but it's incorrect to suggest that there was an earlier time when young men were much less likely to resolve disputes with violence.
I'll note that the initial comments didn't really distinguish between gun homicides and mass shootings. Mass shootings are a subset of gun homicides. This doesn't make much of a rhetorical difference, but it has some policy implications in that there are some forms of firearms common in mass shootings that do not form the majority of gun deaths or gun homicides.
The decline in crime from the 90s has multiple potential causes. One argument is that it correlated to wider access to abortion. Another view is that it was due to better standards when it came to lead paint. It's also been attributed to high incarceration rates (criminals in jails are unable to commit crimes outside of jail), an increase in policing, increase in standards of medical care and better policing strategies.
I really recommend the Freakonomics chapter on that question, as well as Kevin Drum's reporting on lead paint.

I didn't say that we need to accept mass shootings, but the policies proposed by Democrats don't work.
The so-called common sense regulations that are proposed tend not to have a significant impact. Matt Yglesias had a decent summary about this two years ago.

People who own guns, and are knowledgeable about guns, know this. They come to the conclusion that Democrats want to go further. This leads to an increase in firearm and ammunition sales anytime it looks like there might be some restrictions at some point in the future.
Politically, the wisest response would be to lower the temperature, and to figure out solutions that don't immediately fall into existing partisan divides.
