I live around it. I know plenty of people who aren't all the way in the deep end but could eventually go all the way into the deep end. What really helps them not make that final leap is that there is an extremely well deserved stigma against Nazi ideology, the most notorious strain of fascism. There is a gradient and there are plenty of secondary believers whose minds are primed to support a strongman on the elimination of all the bad people keeping society down but would use nicer words to describe it, but tertiary believers who have just been immersed in a deluge of contradictory information can be reasoned with. On this instance at least there is not a lot of tolerance for appeals to popular prejudices which may work out in a general crowd where there isn't a sufficient challenge to it.
