In what universe is it "nice" to snark about what a waste of time it was to rescue and revive them because they were "already dead". By that reasoning, it would be a waste of time to save anyone who had a heart attack, stroke, got poisoned, drowned etc. when there was still time to revive and treat them. As in "Don't bother doing CPR, they're dead anyway."Did Picard's crew really treat people from the 20th century so bad?
What I remember from the episode The Neutral Zone, it was only that arrogant Ralph Offenhouse they were a bit rude against, mostly because he behaved like a jerk himself. They were actually nice to the other two, Clare Raymond and Sonny Clemonds.
This makes Picard look like a sociopath, and a rather bigoted one at that. Riker wasn't much better, and Data did a better job of socializing them into the 24th century than Troi did.
Too bad they didn't have Guinan. She would have done the job right.
