Pity we have to go to these lengths to dissuade the religious from their violent tribal tendencies.
I don't think many congregants in these communities have particularly violent tribal tendencies, nor do I think a walk between these places of worship is such an extreme length to go to, especially since it is entirely voluntary.
The whole idea of such walks as I understand it, is to allow people in different communities to understand that each other do not have these violent tribal tendencies, they are actually perfectly normal people who are more inclined to quiet contemplation than violent outbursts.
Sadly there are some people who think one or all faith communities are filled with brainwashed people with violent tribal tendencies. However, I expect that such people are unlikely to attend, which is a shame because they would probably benefit more than most.
Personally I would rather like to go on this walk if I'm free as I have never visited a mosque and I'm just intrigued to look around, just as I was when The Capitol pub opened their upstairs to visitors on an Open House day. But more than that I think it is great for people with different outlooks on life to have a chat, just like we do on this forum (only in off-line mode) which is why I posted the information on this forum.
