He lost me when he got to how everyone (but him) is pretentious, and everyone (but him) says we, then ends his post with a we, and the whole post reeked of its own pretentious odor......

That aside, most incorporate-XI people aren't barking NONONONONONO at the ideas that aren't from XI, but the anti-XI people scream NONONONONONO if anything is too closely related to XI (even if they never played XI). There are wonderful ideas from XI that they could put in one form or another. There are also terrible ideas from XI that should die in fires.
