I understand exactly what you mean. The broad brush. Of course, if thousands of Christians (or Hindi, or Hebrews, etc.) were in our countries beheading innocents, blowing up stuff, and so forth, well,
those terrorists wouldn't really be Christian, either, but they would be claiming to be Christian, and over time, as damage and death mounted, all Christians would, I guarantee you, be painted with a broad brush, too.
I don't really see any way around that with the extremes to which these "claimed" Moslems are carrying things.
Maybe (speaking of the U.S....I don't know about Australia) if there were a large majority of Moslems standing up denouncing radical terrorists and actively working against them, public opinion would swing more in their favor. Virtually nothing like that goes on, though, unfortunately.
Might be different "down under".

Oh, I liked the reference to the IRA. I never liked them, either. Never understood how our government agencies let them get away with hiding out here and fund raising here.
Must have driven Britain crazy! On the other hand, wasn't Northern Ireland part of conquered and occupied territory? Didn't the Irish just want the invaders out?
Tangled webs, man, tangled webs.
