> by banning it we draw lines as to what is acceptable discourse that excludes a large segment of the population.
I don't think reddit is the measure of acceptable discourse. If the_donald was banned it would just mean that its users would have to find another subreddit or site to use, it says nothing about what type of discourse is generally acceptable. Further, I think it's pretty obvious by now that reddit's problem with the_donald is not related to their political ideas since there other subreddits supportive of the president that have had no conflicts with the site admins (e.g. /r/conservative, /r/republican).
