In particular meditation is very effective for moderating anger. But it's true value comes when we meditate every day. In this way one simply does not anger as easily (though it can still happen). So rather than meditating to deal with a particular issue when we are angry it is better to meditate regularly and not get angry at the issue in the first place.

As a professional meditation teacher I have so many stories of clients experiencing the joy of not being angry as extremely and as often.

One meditator wrote after 18 months of meditating that she'd had a breakthrough. Twice that morning on her commute to work on the freeway someone cut in on her. And she didn't realise until she got to work that she didn't even get upset by it. She just took it in her stride. Where in the past she would have been shouting and abusing that person.

Another client described himself as "that guy who literally has his head and shoulders out of the window of his car yelling at others on the freeway". Over time he too managed to get to a place where the anger did not control him.

Anger itself is an empowering emotion it seems which is partly why it's so attractive. But there is usually a different emotion underneath it that the anger is hiding. Perhaps fear, guilt, sadness. Any number of emotions. Meditation also helps the individual become more aware of those more subtle feelings that are driving the anger.
