And then you bring in tabula rasa, which itself contradicts "born that way." But sure, let's just ignore that paradox. Can we think of other born characteristics we might not find appealing? Quite a lot of personality disorders appear to arise from genetics, and yet you might find someone with Borderline Personality Disorder less than optimal company. Must you tolerate that?
Consistency, if anything, is a poor metric when it comes to anything as complex as people. "Destroy anyone not of my ethnic group" is consistent and simple. Do not fall in love with either.
If anything, the concept of tolerance itself is a trap, creating dividing lines everywhere. Worse yet, it allows someone to feel "just." This is perhaps one of the more dangerous emotions one can experience and consider as moral. A person who thinks of themselves as just is "justfied." Examine the words associated with "justified," even the television show. Consider the history of those who thought of themselves as justified. I feel just, I may then relent on my self-examination. It's a way to sidestep the endless labor of wondering, "Am I doing something right?" Observing, thinking, considering: these are all weights that humans quite naturally want to put down.
How easy, how self-satisfying it is to say "Punch that Nazi!" And of course you first must judge that person to be a Nazi, but even before that you're twiddling your definitions, making them expansive enough to pin that label on someone, all for the simple joy of feeling like it is okay to hit someone, that they are evil and deserving. The ecstasy of self-righteousness ought to be Schedule I.
Give me uncertainty and doubt. Dispel that self-assurance. Going around deciding whom to tolerate invites judgment, as if one were all-knowing and infallible. We are not.
