Someone said Eli Cash in The Royal Tenenbaums is gay. True?

She said it's because Margot tells Richie that their (Eli's and Margot's relationship) didn't work because they quote "Only talked about Richie," meaning both characters were in love with him (Richie), and because of the topless men paintings in Eli's apartment when he's doing drugs. Thoughts? I'm not buying it.
