Answer: Regressive
Explanation: Regressive behaviours and attitudes in life relate to social regressive beliefs that are in fact opposite to progressive beliefs. These are, generally speaking, beliefs that are associated with an earlier, former, outdated state, in this case an earlier, former, outdated, lifestyle.
The Promise Keepers are precisely a regressive social group from the point of view of social studies, by the way an Evangelical para church organisation that stands for outdated family and social values. Apart from advocating the dominant role of a man in the family who has to make decisions on behalf of the whole family which is outdated, they are also against same-sex relationships and marriages, etc. Obviously due to outdated attitudes this organisation is considered regressive.
