Don't know what you're trying to do here. Saying this isn't going to change the fact that the brow-beating rhetoric is alienating young and left-leaning voters.
Don't lie, don't be act aloof towards people you think are on your side, and don't call people Trump sympathizers for having criticisms of Biden. There are people trying to downplay the ongoing harms going on under the Biden administration, and in general under the United States government. Be honest about strategy, and join in on demands that Democrats do better whether or not you plan to vote Biden. Maybe call for a better candidate.
edit: and downvotes for advocating honesty. I'd pretend I were surprised but that would be hypocritical and unbelievable.
