FSP is not an orthodoxy that its members must serve by scoring "points"!
Its members define the broader movement - its goals, its tactics, and so forth.
FSP member "jackassery" is representative of those individuals, not the movement as a whole. The broad public opinion is not wise enough to make that distinction, of course, but that doesn't create any obligation on those individuals to mind their P's and Q's any more than there's any obligation to vote, or participate in CivDis, and so forth.
It's a decentralized movement of free-thinking individuals. Let's not even pretend that any one person or even any one particular philosophy is in control.
