LQ KIX is a long flight with approximately 2.5 K reserve fuel alone, if my memory serves me right. It's unwise to insist on extra fuel on such a long flight cause as mentioned here before you won't fall out of the sky and have about 13 hours to decide what to do or where to go. Other than that I won't endure about rumors or speculations to do the dirty job for you. Fight your fight with the person concerned during training meetings where it should be done. Have at least so much balls my friend.
Don't take it personally take it on the rocks!!!
