Is okay to choose A simply because B is quite literally orange hitler?

Obviously yes. Doing so isn’t saying A is fine, doing so is saying B is worse, and bad is still better than worse.

If you tried to say that there was no reason to be concerned with A because B was worse, that’s a fallacy. But acknowledging that one of two options, while still bad, is LESS bad, isn’t a fallacy. That’s just being realistic.
