In an effort to be inclusive and sensitive to others, groups should consider designating whether gatherings may include alcohol or alternatively, prohibit alcohol use. Members, or their significant others, may have a heightened sensitivity to the presence of alcohol at events. This is especially helpful for groups that have a wide range of members.
If a group has a more narrow range of members, an official ALWAYS policy of alcohol allowed (or at private parties and night events) may be more practical for their particular group. If this is the case, they could list that in their group description and avoid having to repeatedly indicate this for events. The same goes for NO alcohol groups if this is their official policy for all events.
