I did not get that impression at all. I would hope they weren't trying to establish that, because that's not a good idea in any way.
Keep it in mind when you watch it again, particularly when Silva sees the parents' headstone.
I think it's a terrible idea, and I would reject it even if I knew flat out that they meant it that way, but I think it's possible they were hinting at it. It's similar to what some have said about the interrogation scene, where they saw hints that Bond was alluding to being bisexual -- which, of course, doesn't fit the character in the slightest and has very easy alternate explanations.
I'm sure it's going to be one of those "fan theories" which goes around.
