>Tolerance of other views is not a domain occupied by the left. In fact, on many college campuses in the USA the left dominates political thought and won't all any 'unapproved' speakers, organizations, etc... What they claimed they didn't have in the 60's with their 'free speach' movements (but actually did) is exactly what they now, as administrators and professors, won't allow to others. Extremists on the left meet extremists on the right on the opposite side of the big political circle.

Now us on the left would claim that "Tolerance of other views is not a domain occupied by the right".

I think it is often the case that the ones most often heard, left or right, are the ones who are most convinced that they are right (as in correct) and have the ambition to get into a position where they can impose those views on the rest. Very often they subvert a small part of the doctrine that they are espousing that is most useful to them & ignore the rest - as you say, many of the "free speech" movement propose free speech as long as it is in line with their views. On the other side of the coin, you have the "politically correct", who don't want to hear any views that may be considered offensive by any group (usually minorities).

I think it is most important that we all hear &, most importantly, listen to everyone's views, including those we don't like. Until we understand the other persons viewpoint, how do we go about convincing him he is wrong, or at least that we are not wrong.
