I'm curious. (not to mention a bit suspicious) What is your sense of the general sincerity? Do some folks just come for the show, and then, once back home, resort to a more intolerant view, or is the tolerance actually sustained? If there were 9 faiths in town, and you were the one that didn't show up, wouldn't it be a worth it to go just so you didn't look so intolerant, even though you didn't actually agree?
For example, in that 10 minute talk by the host, do some go on a little longer than 10 minutes, and sort of try to convince others, or does it stay cordial? Do some groups come for the meetings, but then don't contribute to joint action plans? I suspect you know what I'm getting at ... all talk and no action. I recall a recent pope's visit to India, where he was all nice for a few days, but then on the day he left, encouraged the Catholic flock to work harder on conversion of the non-believers.
You know how some politicians are ... lots of promises. Then lots of unfulfilled promises.
You seem to have a reasonably good handle on it, so yeah, I'm curious.
