I don't know if your friend would appreciate that you are rampantly posting what they shared with you about their experience on these boards. In any case, at this point it's anecdotal evidence of one member, and you keep saying things as if you are in the "know". Just because you heard it from maybe a few members, doesn't mean you know everything about the drum corps and how it runs.
Did those things happen? Probably. I would say in most corps, someone will have a bad experience or not so great times. You paint a picture that the visual caption heads always yell at the top of their lungs at the members, and that is simply not the case. Where one member had a bad experience, another member the experience of a lifetime. Does that justify the wrongs? Not exactly, but my point is that Regiment is not always "bad".
In fact, I find it incredibly rude and disturbing that this topic has shifted to bashing the visual program. To say that they haven't been successful in feet at all and they are terrible teachers is appalling. Never in any activity have I met so many "experts" on how to properly march and how to properly play. If you're so great at it, please help out at a drum corps of your choice.
In the mean time, please stop this nonsense. G'day.
