I did a similar post on another message board asking if cannabis
should be legalized. I was alone in my battle against their ignorance
some of them still believed the 1930s propaganda I just laughed and
posted facts about cannabis and places on the net they could find
out the truth about marijuana.

But this bunch of morons you have encountered sound like they are
just doing this to get under your skin. These people wont stop at
their quest to make your visit to that message board a living hell so
the best thing to do is not feed into their bull shit and give their
meaningless lifes substance. You are only one click away from taking
these people out of your life.
