Thank you for several salient points made. Changing the channel I oft champion. However, simply changing the channel does not call out or discourage terrible behavior allowing it to fester.
We're audio people not influencing world history. But we do engage those in this neighborhood and should practice a modicum of civility and expect same.
If you were using an elevator and found someone had defecated in the elevator, you could simply use another elevator. The act witnessed and ability to avoid should not render the stupid act acceptable.
Civility in all facets should be the norm, not the exception. Many have simply lost the ability to gauge and recognize their own uncivil behavior. No filter. Witness air travel these days. Wow! Now back to my awesome system and Lightnin' Hopkins. He knew something.
