Did you WATCH the majority of TNG? In the B&B 24th century TNG era - "People can't be fun or act like normal humans' seemed to be Starfleet's Sub-Prime Directive. Hell, most characters (including Spock himself) comment on how emotionless and Vulcan-like Picard was.![]()
Stay consistent, Star Trek, stay consistent.
