@elbanditoroso “Why shouldn’t I be shitty?”
As @canidmajor already said, “human decency.” If that’s not a good enough reason for you, then you should reconsider your opposition to Trump.
“OK, I appreciate that they have a lousy job that they are lucky to have. How does that place an obligation on me when they have broken in on my solitude?”
First of all, they have not “broken in on” your solitude. You have allowed them into your solitude by leaving your ringer on. Second, someone else—in this case, @Berserker—has once again already said it best: “when a friend or a family member phones and interrupts sleep or a meal, do you tell them to go eat shit?” If your objection really is just to the interruption, it shouldn’t matter who is doing the interrupting.
“I see a linkage to Atlas Shrugged here – where Galt (I’m paraphrasing here) says that one has no right to place an obligation on someone else, unless that person agrees.”
Galt was a mouthpiece for an idiot. According to that logic, it’s perfectly fine for me to murder you so long as I haven’t promised not to. It would also leave you with no grounds for objecting to robocalls since the people behind them never agreed not to dial your number.
“So where is my obligation to be civil? ‘Society’ says I should be civil. Flutheropia says I should be civil. Why?”
It seems to me the more forceful question here is “why not?” Surely one needs a reason to be a bad person more than they need a reason to be a good person. But since “human decency” doesn’t seem to be something you consider valuable, then you might consider the fact that the human virtues are good for the virtuous agents themselves, and not just for the external beneficiaries of their virtue.
“Why should I be more polite than the person who phoned me?”
First, let’s point out that you are begging the question that the other person is not being polite. Second, even if we grant the claim that they are not being polite, you have no grounds for complaining about someone if you are unwilling to act better than they do.
”@Berserker, that should have been obvious. You threw in a red herring.”
As the only professor of informal logic on this thread, I suppose it falls to me to point out that @Berserker‘s question is not, in fact, a red herring. Once again: you have framed the problem as being the interruption itself, which is why you’ve been getting so much push back. The question is therefore extremely relevant.
“And to the people who suggested “drop the house phone” – No – I use it for business and other reasons, so I can’t do that.”
Then turn off the ringer when you don’t want to be interrupted (which, you’ll notice, was my original suggestion).
“Finally, I get robocalls and spam calls on my cell phone as well, so that’s not a solution.”
Cellphones also have ringers that can be turned off.
