May be u are the problem, I don't even know how u can say someone's opinion is yewerede, and in relative to whom are you saying that, the best way to understand people is to listen what they are saying carefully, and having a conversation, they might be in the wrong but instead of denigrating them u should try to understand them, if they knowingly reject what u are saying maybe they are protecting something, something that is a key to their survival, people don't just say ow yeah u are right my bad, they will argue till u go away , especially in Ethiopia people aren't used to change at all, but that doesn't mean they are dum, maybe they just don't care about it, there are more significant things in there life, If u really can't stand them , just focus on urself, u are here to live by urself, But don't be comfortable with your thoughts , there is a greater chance for u to be wrong in many aspects
