Parasite?

I got a kick out of the local man's attempt to vent along a major highway in the area.  It seems that a few other people don't like his message, or feel he is undeserving of free speech.

Some one has attempted to destroy his trailer/sign by burning it down on a couple of occasions.


But who can argue with the message?  You are either a provider or one who relies on those who provide. 

The definition of a parasite is:

• an animal or plant that lives in or on a host (another animal or plant); it obtains nourishment from the host without benefiting or killing the host

• leech: a follower who hangs around a host (without benefit to the host) in hope of gain or advantage

Doesn't that accurately describe those who live off the American worker by living off of welfare and unemployment?  So if his message is factually correct, his right to free speech must be their quarrel with him?
