I agree
The authors of the peer-reviewed paper are, in effect, politely trying to say that the "impact nuts" are using Chicken Little scare tactics to protect and increase their funding. Hopefully, this paper, as opposed to the non-peer-reviewed, online psuedo-scientific propaganda put out by "impactists," will help put an end to their Earth-is-in-dire-danger hand waving nonsense.
Whew, I didn't think I could include that many adjectives in one sentence ;-)
