Hate to say it (or perhaps glad to say it) but I am not sure how much impact this talk will have.
In the context of a loyal dub attending 3 days of prolonged witterings this is just one component, yet more same old same old static in the overall noise of "do this, don't do that, Armageddon is coming, preach more, let's all be happified" rehotoric.
Any loyal dub is already conditioned to accept and implement apostaphobia - this talk just hammers an already fully fixed nail in a bit more. There will undoubtably be those who step up the unreasonableness of their behaviour but I bet they are already pretty much black and white on the whole issue.
If you are already DF'ed then you are already dead to 99.9% dubs. If you are in but known for your cynisim then your card is already marked. There is no new info or change of tack in this talk - it's just there to reinforce existing attitudes. The DC is a pep rally and this is just one chant in a large repetoire.
I will be attending my DC soon so it will be interesting to see if there is much comment about it and if my summation is right or wrong...
