@Museek I'm in the first 5 or so years of what is defined as "millennial" but identify way more with Xers.
I see the gap a lot when my 90s born wife talks to my Boomer parents. They can be very dismissive and instead of simply not agreeing just say she is wrong. In that case, the line is maybe justified, but ultimately, and now as it's used as writing off an opinion, it falls into a two wrongs don't make a right situation-in my opinion.
