Is it okay to disagree in front of the kids?

Home is the only place one has freedom to be oneself. Just a wordy warefare without using bad words should be fine as children should know that parents do have differences of opinion and it is ok to have them.

I don't think it is a proper way to disagree and argue in front of children. This cause the children will have the uncertainty to trust their parent as they always argue. The children will confuse who is correct and who is wrong. They will keep guessing and they would not like to see this kind of situation always happen in their life. Children are born to be as pure as a white paper, they tend to follow what their parents said. If parents does not play their role in giving them a proper direction, and good role model. Children will have a bad childhood. They tend to follow their friends and make their friends as their idol. If is was unlucky, this lead to social problem. I think that disagree in front of kids is damaging.

I don't think that it is appropriate for mother and father to argue in front of their children. It can damage the reputation of the mother and father themselves. The children learn through their environment especially their parent. When something can be argued, the children will start argue with their parent too. If not now, maybe tomorrow or in their teenage years. If this happen parent will no longer have control of their children that will result as disaster to their children behavior and future

As long as it is a respectful disagreement, I'm sure it's fine. In fact, it could even teach a child that disagreements are fine, as long as you are mature about them. If you are talking about shouting matches, then no.
