@cicerone imposter,
A non jealous God has no traction ci. If the rules are not strict they have no point and that is particularly important when the rules cover the forbidding of tempting activity.
The football team managers are jealous to protect their positions, as are employers. In either case allowing their players and staff to succumb to obvious temptations such as not training very hard or skiving around at work quickly leads to the loss of their position. It is what a badly run company means and you would be the first to withdraw your investment or cease to buy its products.
The word God implies the jealousy. The phrase "jealous God" is a tautology and its only use is propaganda designed to associate God with jealousy, a negative term, in the minds of not very well educated people. Like "evil" and "cruel".
At your age it is easy being "good". It is not so easy for young men and women.
What the evangelical atheist wants is anarchy in the sexual field and what he or she ought to do in order to be honest is to promote that anarchy as an alternative to puritanism. Which I can do but don't because I have little faith in its economic and social advantages over what we have now. But I am open to debate on the matter.
Talking about pigeons is for pigeon brains.
