I agree with this, but I kind of felt like Dragline's reaction to the car wash girl was so over-the-top that it almost felt like the character was trying to prove to everyone he wasn't gay. I wouldn't have thought much of it if he didn't then go on to spend most of rest the film obsessing over "his boy" Luke. I doubt that's what they were going for and it doesn't really matter much for the story, just something mildly interesting.
Oh I can totally see that, he's diagnosing himself with the notgays. I mean it is '67. And yeah the "my baby boy" stuff, reminiscing about his smile at the end - complete with smile flashback. Maybe it's just his big southern heart but either way find someone who looks at you the way Dragline looks at Cool Hand Luke when he's stuffing hard-boiled eggs into his mouth. ---
