It is entirely possibly that some people support Trump because of his crass and divisive rhetoric, and it's also entirely possible that some people support Trump because of his stance on trade. Is it really anyone's place to demand that another voter change the list of priorities that determine their choice of candidate? Does that not fundamentally alter the intended functioning of the way voting in a democracy ought to work?
I am all for constructive debate on why the policies and character of one candidate makes them more suitable for holding a particular government post, but to suggest that one ought to resort to intimidation, ostracism, marginalizing and other such methods because of an individual's personal choice to prioritize a candidate's agreeable stance on one issue, over a disagreeable stance of another, seems very dangerous to me.
During his campaign, President Obama famously claimed that he felt marriage was a union that ought to be between a man and a woman. Most would consider this to be a highly regressive view, yet voted for him because he was their preferred choice on a whole lot of issues. Campaign officials like David Axelrod later revealed that he took this position publicly for political expediency. Regardless of whether this is true, if one were to suggest marginalizing Obama voters in the way that is being suggested here, I am confident that there would be very little semblance of a community left.
