Libertarians have the potential to be the best people in the world. It is because our core philosophy, when followed, will just about guarantee that result. If we aren't it is because we are not living up to our potential.
Other groups have conflicted "principles" in their core beliefs. Things like stealing is wrong, unless it is government stealing for a cause they happen to support. Or murder is wrong, unless it was government doing it and it was an "honest" mistake (or "they deserved it").
Of course, it is considered very impolite to point out the inconsistencies in the beliefs and philosophies of the "mainstream" groups. That makes libertarians somewhat unpopular at times. It makes those other people uncomfortable, and makes them want to blame libertarians instead of examining their own inconsistencies. Happily, they don't have to agree with us for us to be right.
So, remember your potential, and strive to live up to it. You can point out the inconsistencies, but don't dwell on them since those who do not want to see, won't see. A good example is more persuasive than winning debates any day.
