One of the best ways to judge someone's character is to determine whether he would get along with himself. If he constantly criticizes others for things he does himself, then he wouldn't. And that means he is that lowest form of life, a hypocrite.
With someone like that, you should take everything he says with a grain of salt, and discount his opinions. You certainly don't want to befriend him.
Likewise, if you ever want to know which politicians are credible, look for the hypocrisy.
A politician who has taken both sides of an issue, depending on which happens to be politically convenient at the time, renounces his credibility.
Such a politician is nothing but a spin artist, no more credible as those campaign staffers who will always come out after a debate and opine that their man won.
Whenever there's a racial flare up, ask yourself what would have happened had the races had been reversed in that situation. Would the usual agitators have flown in to make hay out of the situation? Would they be saying the same thing?
Figure out who the hypocrites are, and it gives you a much better sense of the right and wrong of any situation.
For instance, if one side accuses the other of electoral fraud or intimidation, but ignores that which their own side encourages, that's all you need to know.
If one side accuses the other of being "haters," but seems to be much more spiteful and ill-mannered and gratuitously insulting themselves, that tells you everything about the "character" of that side.
Likewise, it's always illuminating to see what the media prefers to pay attention to. Which scandals are kept in public view and which are allowed to slip down the memory hole? Which types of crimes are given a lot of publicity and which are ignored?
If a newspaper or television station prefers to only give attention when the criminal is one race and the victim another, but studiously ignores crimes going in the other direction, that tells you everything you need to know about that media outlet, and their credibility.
People manifest their character through their hypocrisy, or lack thereof, and so do political parties and the media.
