What the famous big blue Boy Scout told to a green Kryptonite? What?? YOU rock!

I've always felt Lex Luthor is intensely threatened by any status or distinction he can't buy, hence the antipathy to Superman's powers and Bruce Wayne's status as old money. Money is Luthor's superpower, and anything he can't obtain or control with it is his kryptonite. Unlike Superman, he takes a proactive view of his kryptonite. It shouldn't exist and he'll do all he can to eradicate it wherever he finds it.

You don't want some tacky Vegas fly-by. You're serious. You're serious about friendships, about your work, your family. You're serious about Star Wars, and you active dislike of Jar Jar Binks---Well, God. Come on, anyone who---You're serious, she continued before he went on a Jar Jar rant, about living your life on your terms, and being easygoing doesn't negate that one bit. You're serious about what kind of kryptonite is more lethal to Superman.You have to go with the classic green. I told you, the gold can strip Kryptonians' powers permanently, but---......Mkae all the lists you want, Cilla. Love? It's green kryptonite. it powers out all the rest.
