I think you have crossed the line into defamation.  What "alt-right neo-nazi" posts are you even referring to?  The term "alt-right" is incredibly new, much as the term "alt-Left" is, and I am completely unaware of any such posts on the DenverPost comment boards.  Had they occurred, they would be bounced by the board moderators very rapidly.  I vote up those posts that make sense and oppose those who seek to initiate force against others, especially when there is no justification for such force initiation.  I have also voted down those who support, or even advocate, criminal activity.  If you advocate for those sorts of things, than enjoy your association with those who have no respect for our society. Admitting the errors of those Leftists and criminals of the past was a positive step; do not support the same kinds of people in today's society if you want to be credible.
