“ESTABLISHMENT REPUBLICANS are siding with the DEMOCRATS on UKRAINE to support Joe Biden getting elected!”
That is a pretense of what other’s intentions are, and not a fact. Reasonable people can disagree about aid to Ukraine without manufacturing what is other’s intentions regarding that aid.
They may also be discerning the truth. Without looking into someone’s soul, you can still assess people’s intentions by reasonable evidence of their actions. I don’t have to look into Hitlers soul to know he was an evil, dictator. The evidence is overwhelming.
