No, that's merely partisan thinking
It's extreme partisanship to let one issue determine whether you're willing to have sensible discussions with someone on any other issue.
It's extreme partisanship to frame that one issue in such stark black-and-white extremes that discussion is impossible. When you portray any opinion other than "stay-the-course" as "cut-n-run" and "defeat" and "surrender", you're not making an intellectual statement of any kind. You're merely declaring your unwillingness to discuss the matter reasonably with your fellow Americans. You're opting-out of the discussion.
