"Too much negativity in this world and you guys are adding to it."
But you complaining about us complaining isn't negative at all... nice double standard you have there.
"Let people enjoy the concerts the way they want."
Here's an idea: how about suggesting that to the people who are RUINING the enjoyment of others? Namely, the people blocking the view of everyone behind them with their narcissistic need to capture their personal extra-special unique snowflake perspective of an event that they'll be able to buy a professionally-shot version of in the near future? And if they're too cheap for that, they can record it when it airs on PBS.
You act like these people have invisible arms and phones (sometimes they're even holding up iPads) that aren't getting in the way of their neighbors' view of the stage. Guess what? That's not the case.
