Some of the
ads
that Russian trolls purchased were for legitimate political
causes.
Sometimes Russian trolls spread fabrications (fake news). It's wrong
for anyone to do that.
Sometimes they support legitimate campaigns for various political
positions. Even though I may support some of those campaigns myself,
I object when Russia does so in a disguised manner.
These ads don't represent sincere support for any cause, not
for Sanders and nor for the troll.
Likewise, I object when right-wing billionaires and fossil-fuel
companies employ people to spread lies. People have the right
present their views, but we don't have to allow the rich to hire
sock-puppets.
