Fergie, I think that your interpretation is wrong, and based on propaganda not fact.
If it were true, why was there no outcry or demand for independence?
Why did the IRB never attract more than a fringe membership?
Why did membership and votes for Sinn Fein collapse after 1908? By 1915 they had so little support that they went broke and could not pay their office rent.

Jim,
had Easter Week not happened, they would have introduced it earlier - why wouldn't they have.

Wrong again Jim.
Ireland was excluded from conscription BEFORE the rising.
Sure it was suggested in 1918, but rejected immediately.
There was not even conscription in the British North in WW2!

The rising achieved nothing, and certainly had nothing to do with Irish exemption from conscription.
