BRTD, different places have different cultures. Religious identity works different ways in different cultures. America's individualism and wide variety of Christian denominations means that religion is weaker as a cultural identity than it is in, say, Ireland or France or Russia.
Do you understand?
But the article posted proves this is not exactly universal in Ireland either.
Also isn't this the sort of thing Marxists would want to abolish? Communists after all have suppressed religion but even keeping nominal religion as some sort of cultural identifier kind of goes against the supposed eventual goal of Communism.
Snowstalker, the great Communist boy, also read the part that you missed about how the Church of Ireland (part of the Anglican Communion) was gaining members. If he is very anti-religion I highly doubt he would think highly of this development. You are basically asking him why he is unhappy that sh*t sandwiches are now being served instead of crapdogs.
