Answer to the OP. No, it should not be cancelled. If anyone breaks a law at the event, they can be dealt with. If the organizers let the event get out of hand, it can be dealt with at that time.
This is a piece on the whole Trump, white backlash, free speech, anti-PC thing that I thought was interesting:

Among the many apparent mysteries concerning the election of Donald Trump to the presidency is the matter of timing.
That people experiencing economic hardship would turn to a racist demagogue is not entirely surprising. The surprise is that it happened in late 2016, when the U.S. economy had mostly recovered from the worst of the Great Recession, rather than in 2008 or 2012, when the economic picture was worse.

The mystery is mostly solved when we take account of the unevenness of the economic recovery and the dislocations caused by long-running structural changes in the economy.
Mostly but not entirely solved because on top of Trump's seemingly odd economic timing we have Trump's odd rhetorical timing.
Trump campaigned against "political correctness," a phenomenon that—judged by the following n-gram and my own subjective impression having lived through the relevant periods—began to decline in significance after peaking in the mid-1990s, roughly two decades before Trump launched his presidential campaign. (Google n-grams cut off in 2008 but the trend is evident.)
His complaints about political correctness were always code for resentment of the groups—racial, ethnic, sexual and other minorities—that political correctness, not to mention simple decency, aims to protect.
Coupling his denunciation of political correctness with acting out the bigotries that political correctness and common decency condemn, Trump's seemingly decades-off timing enabled him to marry his economic nationalism to an ugly ethnocentric nationalism.
Yet even as Trump's cynical denunciation of political correctness serves chiefly to foment hatred and distract attention from the genuine threat that he and his administration pose to free speech, free press and much else, real examples of political correctness appear to have made a comeback.
In this column, I'll discuss three arguable instances based on recent news stories:
