Do you find some people to be insincere? how do you look past this?

Well you have ask about insincerity, and you also seem to be describing people being reserved and private.

When I think people are being insincere, I usually attribute it to they are trying to separate me from my money by fooling me (I don't attempt to look past this. I attempt to see it clearly, in an attempt to not be fooled.) Or else I attribute it to their being afraid in some way that honesty will make them be rejected. If I think that is going on, I try to be compassionate by not judging them harshly for dishonesty, but I don't give them rewarding attention for the parts of themselves that I think are false.

On the other hand. People rarely want to be transparent and make themselves vulnerable to each and every person they encounter as they go about their daily lives. In this case, nobody is pretending anything, but they do hold back on giving their most genuine response. Instead, wearing the mask of "correct and polite" manners as defined by the culture. The purpose is not to deceive, but to avoid standing out from everybody else. I call this being reserved, and I have no need to look past it, as I am that way myself, and don't think it is bad.

I think you and I agree that when we meet someone who is unreserved, always sincere, and who expresses themselves clearly so that you always know their truest reaction to things- such people can be refreshing and entertaining to be around.

People have their reasons for putting up walls and facades.

It might be because they have been surrounded by a lot of distrustful people in the past and that's just how they have become to protect themselves.

It might be something you're doing to make them feel like they need to have this level of distance.

It might just be that this is how they naturally are because that's how they were raised.

Sometimes they might do it to avoid confrontations.

And other times, people open up very slowly to others (which may come off as insincerity), and to them that is normal.

I think the way to look past this is to understand these underlying causes for their behavior and to create a safe relationship where they might feel more comfortable to open up.

You believe you are being "up front and honest" with them. Perhaps you need a reality check.

Approach someone with whom you have a good relationship, and ask them how you come across to other people. My guess is that the people who you find to be reserved are shutting down because they consider YOU to be rude, or intrusive, or both.

Another possibility is that they don't share their true feelings with you because they do not trust you.

A good rule to follow is to offer your opinion or advice only when asked. Otherwise, keep your "up front and honest" opinions and advice to yourself... and to respect the privacy of others.

I ignore people like that and distance myself as much as possible.

yes and i stay away from people like that
