H2O as vapor isn't a forcing, it's a feedback. It condenses out too easily and is present almost entirely in the lower atmosphere and isn't well-mixed.
CO2 doesn't condense out, has a lifetime of decades to centuries, and is well-mixed throughout the column.
Are you familiar with Richard Alley's 2009 AGU Bjerknes lecture, "The Biggest Control Knob: Carbon Dioxide in Earth's Climate History"?
What makes your claim more credible than his science?
