I hear you. I agree that what they wrote is limited to just the candidate and not the voters. I even agree that Trump is unscientific, illogical, fear mongering and dangerous. Wait. I went beyond what you said. Sorry.
But what is the corollary to Trump "rejects evidence and science"? It's that anyone who votes for Trump does the same thing.
You're right that they did not spell this out. But many people who hear the endorsement will immediately jump to that conclusion.
