FCA unity and 'Anglican communion'

[The Ugley Vicar] 11 July 2009--Just a thought, but one of the objections being levelled against the FCA is that it is an ‘unholy alliance’ of Catholics and Evangelicals, sharing a widespread opposition to ordained women and homosexual practice, but divided on almost everything else that matters, such as ecclesiology, theology of priesthood and ministry, doctrine and use of scripture, sacrifice of the mass, praying to the saints and for the dead, lay presidency at the eucharist, episcopal authority, Mary, etc (I quote from elsewhere).

Now maybe I’m missing something here, but isn’t this almost exactly what the opponents of the FCA think the Anglican Communion ought to be —a church which unites people who can disagree completely about absolutely all the above, but who are united in their commitment to the purposes of the Church?

So what is the difference? Isn’t unity in disagreement just what they want from the Anglican Communion? Why does FCA attract the ire of Anglican ‘inclusivists’ for forming an alliance which embraces exactly the kind of breadth they think Anglicanism should include?
