First off let me open by saying Y: The Last Man is one of my favorite series featuring many gay characters. I loved the character of Dr. Mann and her relationship to Yorrick and Rose. Likewise Ex Machina by BKV established that Mitchell Hundred's bodyguard was gay was a surprise reveal. I also know gay people in real life. So, I have no problems reading about gay characters or with gay people in general. Now that that is out of the way....I never wondered when reading Tim Drake was gay bi or straight or even cared. He was the first Robin that I grew up with and I have enjoyed his character. He was established as straight to me. He had that relationship early on with that Russian girl (forgot her name) and a long relationship with Spoiler. So, now all of a sudden he's bi with nothing leading up to it? What when he was trying to get Dick to be Robin back in the day, it was because he had a crush on him? Come on. DC bringing a gay character into the fold is fine. But twisting an established character as bi just because? There was no buildup. Insulting and lazy.
