I never really saw the Frodo and Sam read as homosexual but that article was convincing. I always thought of them as being part of a loving friendship the kind that only exists when two friends go to war. The kind of friendship that can could only be forged when two people who lived in the same place had to go to hell and back together. However, I can see the romantic and sexual elements of a friendship within that context. What I never enjoyed was the dismissing of that kind of friendship as "gay" in the derogatory and dismissive manner. But that is the great part about art is that it is open to interpretation based on people life events and their context.
