This article in the Sydney Morning Herald (by Paul Sheehan, a secular writer) gives some interesting background and analysis of this important issue.
The number of Middle-Eastern Christians in Australia is less than the number of Muslims, but is comparable. This could become a significant voting block if Labour continues in the direction it is going.
The question to ponder is whether other Christians in Australia will see this as an important political issue - and add their voice to that of their Coptic, Macedonian and Assyrian brothers and sisters - I hope they do.
Certainly it seems odd to me that we are accepting significant numbers of Muslim 'refugees' from the Middle-East, when the Christian minorities are the ones being persecuted and are fleeing their countries by the hundreds of thousands.
