This is a trend I would expect too, but the data does not appear to support it. Gun control has actually become consistently less popular over the last two decades[1]. I actually don't have a clue why, as it seems to counter other various demographic/political trends.
It correlates with a massive decrease in crime. It's interesting, but I live in a fairly mixed-income and higher crime area and guns are very unpopular here. I think ultimately it's some sort of weird reaction to extreme safety. Our brains start creating fake risk when we don't have any in our lives.
