user14318: I find myself in conflict with the Buddhist idea of letting go.
If someone insults you, is rude to you, insults a loved one, harrases you or a loved one and so on. According to Buddhism, we should forget about it. Past is past.
But then on the other hand Buddhism also mentions that we should be courageous. And sometimes being courageous can lead to further pain. Say that you confront people who insult a loved one and then they stab you.
I'm having a problem to decide when to confront and when not to.
For now, I always let go and I feel like a doormat sometimes.
Thank you.

user738: So, of course, I can quote some Sutta and say this is similar to your situation and so-and-so happened with Gautama Buddha, da-di-da-di-da etc., and so you must do this or that. But I want to get practical here.
I think it is important to understand this. What you are essentially trying to do is looking for a "philosophy" that is a hammer-on-a-nail for every little situation we are faced with. 
In this light, you are seeing this "concept" of Buddhism in your head, which has useful texts regarding certain aspects of life. Also it is a fact that times have gone on. The world is constantly changing.  Reliance on a certain philosophy and buzzwords (like "let go") and the general people's perception on Buddhism per se, can cause conflicts like these.
That's why my answer here is a question back to you, because we need to think this through carefully. Perhaps it is your "concept" of Buddhism as this philosophy that asks you to "let go" is the problem. Why look at Buddhism for somebody insulting you?
Too many words are going around like this today. "Let go", "let it be", "mindfulness" are all these so-called Instagram/Twitter hashtags these days. Perhaps we are making a mistake in holding on to some concocted philosophy which you don't know is right or wrong. 
Situations in your life and Buddhism as your "concept" are two separate things, don't mix them up. :) Try to change your idea of Buddhism. It is not trying to tell you what to do when someone insults your wife. It is trying to tell you about samsara and liberation essentially.
Finally, coming to your situation of insults and everything, don't look at Buddhism/Hinduism/Christianity/whatever for answers. Will the answer ever be there in the texts as to what is the right thing to do? Has it ever been that way? If your answer is yes, then probably I cannot help you.

There're creative ways to both let go while not being a doormat. Humans are still animals with big brains. And like animals, the predator (or bully in the case of humans) only picks out the weakest one in the herd to prey on. This applies everywhere, in school, at work, at wars, etc. So be strong, both physically and mentally. It's simply human nature that if one sees a doormat, he'll step on it. Why? because he can. So do not display any outward sign of weaknest. And no, this is not violating the Teaching. You can be strong while not being angry at the same time.

user254: I think the best message on this topic is the Akkosa Sutta: Insult (SN 7.2) -- about insult and anger:
The first message is that, in order to not accept an insult, don't (violently) reject it, just don't participate in it
And secondly,

You make things worse
  when you flare up
  at someone who's angry.
  Whoever doesn't flare up
  at someone who's angry
      wins a battle
      hard to win.

For what it's worth I think that my "martial arts" teacher taught just about exactly that same message -- about anger, fighting, and so on.
