It's also impossible to be productive when your interlocutor has already made their mind up about you. As someone who is marginally right of center, I have to take your statement as warning not to bother; based on your sweeping marginalization of everyone on the right, even if I had a reasonable argument, you would not hear it. I think your opinion is almost universally held here, and is a good reason for me and others with differing opinions just to stay out of it, at least those who like to make good use of their time. So continue to have your sport with those too foolish not to just leave, you'll only see me in rare times of indiscretion.
Think about what dank said to this:
"No, it's actually really simple. Don't post misinformation and don't post logical fallacies. I pretty much only engage when people do one or both, and as you can see, lifer is in my rear view awhile now."
Whether you leave or stay is irrelevant to me, I care only about you as a person with feelings, only about how your assumptions affect your happiness. This is why I have done what I can to support your moral feeling that pilloring people for positions they take out of moral concerns liberals don't share is wrong and counterproductive. See my posts above. But look at how a liberal mind like dank's sees the issue:
He is focused on the truth. He is not looking for what positive moral values conservatives are trying to defend and stereotypically do by rationalizations, knowing in their guts as they do, that their moral concerns have real value. He focus only on the truth of what is said and not the motivation.
And, now, if it is stereotypically true that conservatives will not face the truth or falseness of their argument because they know the truth of the worth of the values they defend and are impelled by moral concerns to defend them, coming up with whatever rationalization to do so, then, instead of being treated as Knights of Martyred Virtue, or Christian Soldiers or whatever saintly warriors you would like to picture. they will, when engaging that stereotype, only be seen as liars.
As long as you cling to the notion that conservatives should be treated respectfully, and liberals extend respect only to truthfulness, unconcerned with the underlying moral motivations, and conservatives engage with autonomous regularity is deflections and rationalizations, you and they are destined to feel like victims.
All of this in my opinion is just a war between people who value truth and respect differently on a moral scale and in such a way as to deny the validity of the 'others' moral concerns. And I don't think there are many people who have the slightest idea how they came to value one thing over another. It all springs from unexamined assumptions.
