You might have a point IF THEY VOTED for someone guaranteed to lose. Then they could pretend they are above it all.Those that abstained in 2016 expressed a political choice just a valid as anybody else's.
Not voting at all is not a "valid" choice, though I urge all who disagree with me to make that choice.
I didn't go to a movie last weekend and so I guess by your reasoning I didn't make a choice about what was playing?
