In my experience, yes, the irredeemable bigot is rare. For everyone else, regardless of whether their political views are unknown to you or they are threatening your personal way of life, the world will be a better place for you being good neighbors with them. Not to mention that it will improve your own living situation as well.

Most bigotry doesn't come from an inherent maliciousness or evil. It's often just limited experience and never having had reason to reflect on one's views. If you instinctively go "fuck off bigot", you're not only not helping, you're their mirror image.

To be clear, there's a point at which you have to be intolerant of intolerance, but starting off with that is not only counterproductive by reinforcing echo chambers and increasing division, it also makes you not unlike the thing you're opposed to.
