A lot of very misguided Americans brought into the IRA’s fundraising campaign. How they could not know the money raised went to commit acts of terror is beyond me. King would do well to do some major groveling over his support of the IRA.
However his past support of them does not invalidate his call against today’s Muslim terrorists.
When they were killing members of an occupying foreign army, they were freedom fighters. When they started targeting civilians, they became murderers. How hard would the NYT (for example) investigate and report on fellow Marxists?
