im not stupid

You are totally right. There is not much anyone can do to stop these kind of things from happening. People may think it doesn't bother people but it really does and there is nothing you can do about it so your anger builds up. Something as simple as calling someone stupid can cause all kinds of trouble. My advice to you is pay no attention to people like that, even though I know it is not that simple.

I hate it, absolutely hate it, people think I am a walkover, people think I am easily controlled and that I am gullible, naive and easily lead, therefore I am stupid and they look at you as though you are a town fool or a total imbicile, my ex used to treat me like that, and would treat me like a child when I tried to offer my opinion when we were talking with friends. It was embarrassing and I hated it. Part of the reason why I am taking up psychology is too help me understand why people treat me like this, I am obviously giving off signals or NVC (non-verbal communication)
