I think you meant "repels", unless you meant "refudiates", though perhaps your finger stumbled in the middle of "repls".

"refudiate" isn't a word (though it appears to be a Palin-ism -- http://www.urbandictionary.com/define.php?term=Refudiate). Perhaps you meant "repudiate?"

I have at least the excuse of not being a native speaker, contrary to S. Palin :) Thanks for the correction.
