Yeah yeah, it's totally a preference thing. I can't ignore it, because I use the scroll wheel a _ton_ (have you ever used the middle-click autoscroll thing in Firefox? it rules). So sometimes the scroll wheel gets accidentally clicked and I paste some junk into the middle of the document I happen to be scrolling through. I'd much rather have a strong, confirmative action like pressing Ctrl-C and V to interact with the clipboard, rather than overloaded functions like highlighting text or interacting with the scroll wheel. It sucks, but after 10+ years on X11, I've mostly gotten used to it.
