Don't understand this statement

"
Although in many respects playing different language games, the family resemblance linking all of the above a concern with issues of self-determination, autonomy and assisted decision-making, and by extension the propagation of the belief that people with learning difficulties have the right to act and be treated by THE society in an age appropriate manner"

What does the bold-faced clause here even mean? Along with the context about family resemblance linking all the issues as a concern?

Also, what exactly does the "family resemblance" here mean? Resembling to what?
Yet another question, the statement starts with the conjunction "although" and yet never makes a conclusion on
the said facts factor into.

Any help please?
Thanks.
