That's certainly a point of disagreement. I think this absolutely should be ignored. Him saying the ISS should be deorbited after 27 years rather than 30 years

That's certainly a point of disagreement. I think this absolutely should be ignored. Him saying the ISS should be deorbited after 27 years rather than 30 years isn't a disqualifying opinion. Freaking out at perfectly valid opinions or actions is a bad thing to do. If you are constantly screaming over nothing, you'll be tuned out, and that's bad for when there are real things to scream about.
