Christianity and its repression

Christianity tends to cause followers to repress their feelings. For example, there is often a pressure being put on people to forgive others in Christian circles, without giving them room to come to terms with their feelings. Maybe those who condemn others for not forgiving have forgotten or ignored the fact that the book of psalms has a number of examples of the psalmists calling upon God to take revenge of their enemies or destroy their enemies. It is testimony that humans need to find outlets for expressing their hurts and sufferings in safe ways. It is unfortunate that there are Christians today who do not encourage others to feel their feelings and instead shame them for not following their so-called "positive" messages about forgiving others and moving on, without giving them freedom to do so in their own time and space. This only tends to cause the feelings of resentment to bottle up and explode later on. Maybe it is why Christians who repress their own feelings become callous towards others because they have not been in touch with their own humanity too.
