Truth is not based on what we feel, but what is. Therein lies the problem. To some, there is nothing absolute. Relativism has taken its toll even among conservatives. I can mislead as long as it helps me 'win' the argument.
There's no way to debate a relativist.
Luckily we’re not fighting WWII. Then any supporting the Allies would be accused of being Stalin-loving communists by this “logic.”
