1. Racial Intolerance
Klingons are racist. Yeah, I said it. Every encounter with another race always includes chest-thumping, roars of triumph and then terminates with the emphatic statement: "WE ARE KLINGON!" Remember Commander Kang in the TOS episode, Day of the Dove? Outnumbered, half his crew is wounded and armed only with swords; Kang rallied his troops to nearly take the Enterprise from Captain Kirk. What did he yell? Yeah, you guessed it: "WE ARE KLINGONS!" Now, to be sure, Kang and his crew were rapidly regenerating while they were under the influence of an alien presence, but there was no mistaking the tone of racial superiority in his screaming. Klingons don't bow to any race. Klingons don't make any excuses for themselves. That's definitely admirable, but at the same time, it also doesn't allow them to see the strengths in other races. Living with someone who has this mentality doesn't make it a comfortable partnership. I mean, it's bad enough to be nagged into doing something, but to be told that it's because your race is worthless is just unbearable. Sharing your life with someone requires compromise, consideration and a person who doesn't think that your species is craven, spineless and weak. You need a person who thinks about you look, not how you would look impaled on their family sword. You want to share meals together, not hunt them together. Don't live with a Klingon; you'd be happier sharing a sleeping bag with an amorous hyena. K'plah.
