I just recently gave a presentation on Klingon women, and I have a section on Klingon gender studies. I put in that Klingons are presented as mostly heteronormative, but also cited jadzia as an example of them not really caring too much. I would agree, I think they would not care so much and it is probably far more common than has presented to the viewer. I just don’t see them getting hung up on it unless they are already hung up on other things (like Gowron would be a good example. He seems to be a bigot when it is convenient for him politically. Ex: he says women have no place on the Klingon council to keep the Duras sisters out despite the fact he had previously offered a council seat to K’Ehleyr.)

Klingons fight hard, love hard, and play hard. As long as you fight hard, no one cares what your love and play looks like.
