Why must I be tolerant of intolerance? If Trump wants to ban Mexicans and Muslims, why am I not allowed to try to ban every trace of Trump?
Expressing the desire to do something (ban Mexicans and Muslims, in this example) is not the same as doing it.
The issue is not tolerance of intolerance. It is tolerance of other people's ideas and beliefs, whether or not you agree with them. Tolerance is, by definition, the willingness to allow (not necessarily accept) ideas which are contrary to your own. Acceptance of ideas which are similar to one's own is not tolerance; it is agreement.
You may certainly "ban every trace of Trump" within spaces you own or control. Attempting to do the same anywhere else (especially in my space), is simply an attempt to exert control over others and -that- is an act of intolerance.
It's probably pretty safe to say that you will not vote for Trump, assuming you are a US citizen. That's fine. I cannot see myself voting for him either, however, for different reasons.
If you do not find that argument compelling, let me try another one. Let him talk. If you are right and his ideas are so repugnant, then those ideas will simply die in the open air. To quote a well-know political commentator, "Sunlight kills bacteria."
