I think the "rule" of no politics or religion being discussed at table came about because so few people could discuss these subjects without resorting to shouting, quarrelling or even fighting - none of which is good for the digestion!
As I posted before I had some very interesting discussions with someone I met on holiday whose views were totally opposite to mine - these included religion and politics and yes we did discuss them over dinner. The difference was that we both acted like adults and listened to each others views explaining why we each disagreed, or on some occasions agreed. Isn't that what discussion should be all about - not resorting to insults which smacks of a child throwing its toys out of the pram in a tantrum! (No I am not directing that comment to anyone - it is just my opinion)
