I'm not a Trump supporter by any stretch but mother of god if "crooked" which is literally just an adjective and is pretty appropriate when applied to Hillary Clinton is now considered a slur all these angry white people might just be on to something.

No, but calling your opponent's supporters "deplorables" and repeatedly insinuating that they're all bigoted, sexist, racists was.

See that Trump and Trump supporters largely limited their name calling to Hillary, whereas Hillary and Hillary supporters largely blasted on Trump as well as his supporters.
