You are not obligated to do anything. If, however, you believe groups that use 100% of the available sapients will always outcompete groups that use 50% of them you will probably, of your own conscience, gravitate towards those groups that do not tacitly exclude those 50% and avoid those that do. When one side tacitly approves of rape threats and murder threats for people who speak out they make it pretty darn easy for me to choose.
