I thought you were joking (and maybe you are) but now that I think about it, that's a really good life philosophy. Tolerate behavior in others beyond what you would engage in yourself.

Of course, this works better for social conventions like "call me by my last name" or "pay for your date's dinner" than for stuff like "don't be gay", which is sadly what's more associated with conservatism in this country.

That's how I try to operate. Everybody should get a break but me. There's a word for giving yourself a break for bad behavior: rationalization.
