Tim Alberino gives his Christian interpretation of Barber's claims. (He also interviewed Elizondo recently, sharing his views that the Grays are evil.)
He makes some good points, re: the emotion of the experience, pointing out the obvious: you cannot judge the intentions of another being based on the feelings they produce in you.
Now, in the full interview, Barber makes it clear that he doesn't even know if the craft was occupied. It may not have been. So here what I think the options might be in this case (broadly speaking - I can think of several more variations):
1) He encountered a negative entity that made him feel these emotions.
2) He encountered a positive entity that made him feel these emotions.
3) His proximity to the craft simply opened up his higher emotional center, and the emotions were a secondary effect not directly tied to the craft or its "pilots."
I lean towards option #1. He says repeatedly that the connection he felt is still with him, that he feels the NHI themselves want "disclosure," and that he and his team will facilitate this.
If that happens, I hope Trump will establish a UAP czar (the rumor in the UFO community is that this is a very real possibility), and that he puts someone like Grusch or Elizondo in charge. Barber sounds like he is being used by beings for purposes he does not fully understand. Guys like Grusch and Elizondo seem to have enough objectivity to be cautious about NHI intentions.
Alberino also throws out some interesting speculation on the Nordics: that they are "angels" of the bible (good and bad), or that they are a human antediluvian race that either survived underground or went off-planet. He shares stories he's heard from the villagers of the Andes mountains who describe Nordics arriving in flying saucers, healing the sick, and taking off. He points out that it can be difficult to tell whether an angel or Nordic is good or bad, thus the biblical advice to "test the spirits."
