Is this a religion thing? I don't do religion.

Depends on how you look at it. More belief than anything else. But respect that you do not do religion for one reason or another. Religion can give people hope, it can let people down, and can cause wars so totally get that you do not do it.

they became the world's richest organisation during their time through merchant trade routes which prompted them being turned over by the Catholic Church. they're supposed to have had the world's largest fleet of ships and quite a few monopolies.

anywhere in London where a place or building is called temple was established by them, maybe further afield too.

I don't know whether they were smeared by the church or genuine heretics, both opinions are held about them depending on who you read. they did however manage to exist militarily in Jerusalem and rule it for 100 years being formed out of members of the first crusade. it was only subsequent crusades that grew to be despised by the locals I've read.

Bravo and well read Mel. It was the locals that despised it . Which leads to my original question wrong, or right.

I'd always assumed that to some degree relations were pretty good between the first crusade and the locals, they would have been outnumbered several hundred to 1 over there even with a castle.

They certainly would have been. The castle, and temples were bricks, and mortar. Both built on strong foundations. But where the bricks, and mortar failed , faith, and belief, and god was the strongest foundation that they could have ever had. That is what kept them strong until the end. Well in that chapter of history any way.

Great, not just good.

Agreed Boza great but not good. What would you say would be a greater good if you do not mind me asking?
