It is useful to start FSUGs, whose activities could include users of the free *BSD systems as well as the variants of GNU. It is also useful to start GNU/Linux User Groups.
Right now the LUGs teach people to think of the system as "Linux" and teach them to think its sole purpose is its own success. (For example, ILUG-Delhu voted to endorse the non-free program KalCulate.) LUGs capture the energy that comes from enthusiasm for the system, and focus it in a direction that doesn't support liberty or GNU. We need GNU/Linux groups in order to direct some of this energy in a better direction.
