How to deal with people, or should I just ignore?

I was thinking about this for a while; how to deal with people to the point where it will not drive me insane? People think that I should just be the listener and agree with them. When I address my opinion I get ignored and that person simply changes the subject like whatever I said is completely unimportant. Also, they keep talking and expect me to agree with them all the time. It gives them the satisfaction that I am just the listener and I obey them. I am just totally fed up with people’s behavior and wondering what I can do to stop it in a better way. Ignoring didn’t help. Anger didn’t tell. A shocked face and stuttering to answer anymore didn’t help.

Here are a few scenarios that I had to endure the past few days.

1. I was talking to this person about random things I usually don’t have anything in common, but friendly talk to pass the time when he brings up a subject. I listen and I answer. However, when I start a subject, he completely changes the subject back. Although the conversation ended and it was becoming repetitive. It is like I am not allowed to state my opinion or bring up a conversation and I am immediately disregarded. Why the hell are people like that?
2. A friend of mine keeps calling me with her problems and life events. A lot of them are repetitive events and mistakes she continues to make without thinking. Maybe it is her luck. I am not sure. To me I don’t agree with her lifestyle at all, but I just listen and I tolerate her because I know deep down inside she is better than that, and she listens to me whenever I need her. However, she calls and tells me almost the same story and same problems again early this morning. I just listen, and I kept saying, “ok”, “why”, “didn’t that happen before”, “are you ever going to get over him?” After a few minutes she realized I completely lost interest in her conversation. In reality, I just couldn’t stand listening anymore and I wondered how long do I have to endure listening to this. If I tell her to stop, she will think I am a bad friend and I am ignoring her. At times she doesn’t tell me till after the event by a few days cause she knows I seldom agree with her actions and it gives her time to get over her problems first before she tells me. At that point I am completely appalled at what she did and I just tell her, “what do you want me to do now?” In reality, what am I to do? Sympathize? Have pity? Talk some sense into her? I tried it all, but no use. Born a stubborn goat will always be stubborn goat.
3. Continuous ridicule by my mother. Dear God when will it stop! I keep telling her to leave me alone. To stop telling me what to do and what not to do. She doesn’t understand why I get mad and yell back. It drives me insane. It got to the point where I immediately snap before she finishes the sentence. What does she do after? She gets mad and starts praying to God to help her deal with me and it is better off she is dead and not have to deal with such rotten kids. Etc, etc.. You know how Arabs are. They can’t smack their kids after a certain age, so they start throwing blasphemous phrases to make the situation worse! God when will it end!

Why are people like this?

I need to meet new people who just want to talk normally and actually want to have a unique and different conversation from day to day!
