Dealing with Difficult people

Why do some people feel the need to put others down? Have you ever had an argument with someone, and instead of getting to the point of the problem they immediately point out what you did wrong or point out your flaws and put you down. I came across a website today
http://www.life-with-confidence.com/people-who-put-you-down.html

And the first thing it says;
"The first thing to know is that a happy, self confident, person does not put others down .
Some people are very negative about others because:
- they need to make themselves feel like they're in control or more powerful or to cover up their own insecurities - they’ve experienced a trauma of their own in the past and they don’t know how to deal with the pain so they'll hurt others as a defense mechanism"

So take a look at the person who is treating you this way and you will probably see that they have many issues of their own! So how do we deal with them?

We all no that its really hard to just let it go, we all want our say tooo. But the article says to not let them get what they want, which is a rageful reaction LOL Ive had my shares. Instead tell them you will not accept what they just told you, or tell them how you feel and to keep the argument strictly about the situation....

If your like me, this is hard especially if someone comes at you hard with the put downs how can I not react!... This will be something I will be working on for myself, because none of us deserve to let others control us with their words ;)
