Something like this is a very delicate process. The people to talk to are the GM and the old/new raid leads... nobody else. Don't make a forum thread, and ESPECIALLY don't bring it up during a raid! Have a private chat, maybe make a party in WoW or on Ventrilo/similar, and discuss what the guild feels like.
Maybe the old raid lead has been waiting for someone to step up. Maybe he's been having issues outside of WoW which has affected his raid leading. Talk it with him, maybe see if he can improve himself first before getting replaced. If you just replace him instantly he'll get super offended, then if the new guy turns out to be terrible then you could be without a raid leader entirely.
Give him the chance to improve first, ask him how he feels as well. A private discussion between the guild leader and the old/new raid leaders would be very beneficial.
