It doesn't matter if the group is a church or a gang or a sewing circle or masculinity itself, asking members to dislike, disown, or distance themselves from another group of people as a condition of 'belonging' is always about control and power. I think we have to question the intentions of any group that insists on disdain toward other people as a membership requirement. It may be disguised as belonging, but real belonging doesn't necessitate disdain.
