If anything makes a point for a moderator being able to just cut a feed, it is those types of arguements. Most moderators just want to keep the echo running, on topic, and with a minimum of fuss. Making them work twice as hard so that a legal type can have the last word is annoying. Probably more annoying than the odd attilla the moderator. Besides, ever sysop or user can cut an echo at any time they want.
Communication is a two way street.
Mr. Ari Pollak has submited an internet article, and offered to write a weekly one if enough interest is shown. I have a question for him, or for any other sysop listening. The poster logged in just as if it was a telephone. The internet is THE center of the information superhighway. Going by that route, there can also be many different problems along the way.
