why does EtBr stain also single strand RNA?

Without looking it up, here's what I'd expect.  The bases are hydrophobic
enough so that even in single stranded DNA and RNA they are going to want
to stack to minimize their interarctions with water.  Because the bases are
stacked, dyes like EtBr can still intercalate.
