I think the problem here is that we all get very angry when we are taken without permission as probably 90% of all abductions are within this scenario.
As an abductee myself i have come face to face with greys and reptiles i found the reptiles more worrying.
The greys although still a fret were more like working drones, but this still makes me angry
Taking children doesn't mean nothing to them, they are emotionless, also these kids parents were more likely to have been abducted themselves, these thing runs in families.
I have often wondered how i would feel if a species actually took the time out and asked me politely "Please come with me, i promise not to hurt you and i will return you safely" ha ha! but then i'm only dreaming. This would never happen.
Having any experimentation done to you without permission is downright assult!
I could never think kindly of any entity that chose to treat me that way.
