It's more like, in a world with exactly eight soup kitchens, the "soup kitchen support union" specifically excluding one from its support network and issuing a statement that, despite its soup having similar origins and ingredients, doesn't qualify as soup in to today's palette unless consumed collectively by all of society.

They're not the American Bill of Rights Union. They have a conception of what "civil liberties" amounts to which many sympathize with, and they fight for that.

If you think they do good work in that arena, great!

If you think they do good work in that arena and others do good work elsewhere, hey, you know what? That's still great!

(And if you think they do poor work, or work on the wrong goals or whatever, well, of course that's your prerogative.)

You're stretching the metaphor beyond its breaking point. There's no limit on the number of civil rights organizations out there; the ACLU does not have any exclusive right to sue over certain issues or coordinate other groups, it's just particularly old, effective, and respected.

If you're particularly worried about the 2nd amendment there are organizations (extremely powerful and effective organizations at that) to sue on your behalf.

I don't see the problem there, when that one particular soup kitchen, for various reasons, has several other support unions which are dedicated exclusively to supporting that soup kitchen, and ignore all the other ones.

It makes perfect sense that the "soup kitchen support union" would then concentrate all their efforts on the other 7 soup kitchens which don't get nearly as much support.
