I think my wife and I should pay more in taxes. I also feel that I shouldn't die on my sword and voluntarily pay more in taxes whilst others in my income bracket don't. There is nothing contradictory in this. But suppose you think it is hypocritical of me to think tax rates should be higher for people like me while not voluntarily paying more in taxes. At most you can conclude that I'm a hypocrite.
My hypocrisy does not detract from the veracity of the belief that taxes should be higher for people like me. That belief is correct/true/valid or wrong independent of my hypocrisy.
