Group rights are common in our society. Same sex marriage, for example. The right of journalists to protect their sources. The right of a nation to self-determination. The right of the police to bear lethal arms. And on and on... It is for us to determine whether a particular group merits a particular right, but if we're having an adult conversation it's not OK simply to declare that there's no such thing as group rights. 

Similarly, there are group duties -- for example, my duty as a member of the fight club is never to mention the fight club. Members of a hospice may define their duty as regards medical assistance in dying. This is not an issue of "controlling minds", and to frame it as such is unhelpful.
