I would contend that whether a group is more or less inclusive does not solely depend on whether they have failed to include the homeless, black people, old people, religious people, etc.

It depends on whether the parameters of your group accepts more people, and another measure might look at whether or not your group accepts more kinds of people, or some weighted balance.

Also, if we were to add in some choice examples, I'd look at how the teaching profession treats LGBT people. Such people are under risk of being considered pedophiles. It's probably a career-killer, and any administration that backs that teacher would need strength to resist parents.
