Call "white men" as a class "angry"? That's perfectly okay: http://www.huffingtonpost.com/andy-schmookler/angry-white-men-on-the-ri_b_5840252.html

But when Warren Buffet calls one woman, Sen. Elizabeth Warren, "angry," that's sexist: http://time.com/money/3728497/warren-buffett-elizabeth-warren-squawk-box/

And if that's how it's going to play in the next presidential election -- where any criticism of a female candidate is denounced as "sexist" -- then we have to ask if the folks doing the denouncing are really ready for a woman president.
