The IRA has been around for over eighty year with various splits and splinter groups which all are calling themselves "IRA" to confuse the issue.
As I understand it, most of the folks in Ireland reject the notion that the current IRA is the same IRA from the 1920s. In fact the IRA from the 1920s is refered to as the old-IRA in deference to todays IRA.
Some resources to seem to try to maintain continuity, but I think that's a bit of a stretch.
We do agree that there is a terrorist network around the world that is communist/socialist driven. That still doesn't make the Muslim extremists (more accurately called - IslamoFascists) Communist rather than Muslim adherents.
We agree on most of it. And we agree that it goes under-reported. Digging into the group A.N.S.W.E.R. makes it pretty clear that they are all one big happy family. Even the PLO is supported by this group, and possibly even supported by the PLO. That still doesn't mean the PLO or Hezbollah have sworn off Islam and now only follow Communism.
You take care.
