Trip was not forced, nor was he drugged. He was of age and gave consent. He just got knocked up. I think they just dusted off an alternate script of Voyager's The Disease. Since Trip is the White Harry Kim, it worked well enough. The humor is neither sophisticated nor sidesplitting, though.
Every Klingon who doesn't act like one of those idiotic TNG/DS9 Klingons is fine by me.
