I can see your point about disrespect issues, but I get extremely frustrated with people who think that it's perfectly okay to disrespect me and touch my expensive personal gear. "No, that one inch hollow aluminum pole will not hold your body weight, and further more, it's mine, please don't touch it." - doesn't seem to apply to the concert going public.
I don't understand where people get off and think that it's reasonable to see a pole and have to touch it. People don't go around groping other people's cameras or cell phones, but they have to get their grubby mitts all over mic stands, and that's just not right. Taping would be a perfectly safe hobby if not for this particular societal anomaly.
