If you don't want people implying that you're insane, don't say insane things.Similarly, if you're talking too loud and someone calls you out on it take the L and don't complain. You even said that yelling "X DIED LAST NIGHT," is not fine, well that's exactly what I'm talking about. If you're talking loud enough that someone ten feet away who isn't listening in can hear you then you're talking too loud and, again, should take the L if someone complains.
It's just like free speech, no-one can stop you doing something, but that doesn't make you exempt from any and all criticism. In your efforts to stop the "policing" of volume levels you've started policing what people can and can't complain about.
Oh, and thanks for calling me insane.
Ten feet is not far. At a normal voice level you're still well within the clearly audible range at ten feet.
If you're complaining about hearing someone ten feet away, you're complaining about reality.
And that's not getting into your utterly bizarre free speech argument. Which honestly is just too inane for me to respond to and will only lead to circular arguments. (i.e. your criticism isn't exempt from criticism, etc, etc)
