No, it's not. Not when that person has other horrific ideas that should not be supported by any sensible human being. Not if that person is a pathological liar that jumps from one idea to the contrary on a whims notice. Not if that person uses racism and violence as a platform. Not if that person openly calls for committing war crimes and invading other countries. It's - and I'm deliberately choosing the godwin route here - akin to saying "It was ok to support Hitler because I support the construction of the Autobahn."
