It is a tough issue.  Trump's campaign rallies are hives of violence and bigotry.  His campaign is supported by the KKK and numerous anti-immigration hate groups.  When he and his supporters embrace such racist ideals it is difficult to say that a "Students for Trump" club is much different than the "Anti-Muslim" club or a "He Man Woman Haters Club".  Trump's campaign events are closer to a hate rally than a political rally.  You have to draw the line somewhere.  Trump needs to draw the line, but he so far has refused to do so.
 
The voice of love needs to be louder than the voice of hate.
