I was watching an interview with someone in politics who said he had become the lightning rod, and I was not sure what that meant but looking up the meaning, I wonder how is that different from being a scapegoat?
EDIT: I'm asked to say why the following suggested link is not the answer. That one is not about the difference between these two terms. But I do see an answer that references both terms:
"A lightning rod is someone who attracts a lot of criticism, in particular in order to shield other people (like a literal lightning rod diverts lightning harmlessly into the ground). It is thus related in meaning with scapegoat, i.e. someone who is blamed for the mistakes of others."
So is this the difference then that lighting rod (purposefully) attracts the criticism to shield others, almost heroically, but scapegoat is person who is blamed/criticized by OTHERS?
