Actually, my main issue with pre-determined traits is far less because I find it offensive, but more because it would seriously reduce the replay value of the religion element of the game. i.e., you play each of the 7 religions-with their traits-once, and then all of their enjoyment is pretty much gone. This, ultimately, was the problem with the Governments in Civ2 and Civ3. They had pre-set 'traits' which everyone quickly got used to.
Here is a much better solution. 12-20 traits (6-10 of them 'mutually exlcusive' from each other), from which you can either choose-or acquire-if you found a religion. For example, lets say you get Code of Laws first-and found Islam. You consider that your civ's Leader is Expansive and Creative, so you look through the list of traits and pick 'Evangelical' and 'Baroque'. The first trait grants a bonus to city conversions and the building of missionaries, but you get a penalty to happiness in cities with a different religion to yours. The second trait gives you bonus culture from religious buildings, but increases the maintainance costs of those buildings. Then every 500-1000-or whenever the Holy City changes hands-the current controller of the Holy City gets to change that religion's traits-at the cost of 1-turn of anarchy (but they must belong to the same faith as the holy city they control).
Alternatively, the traits are acquired via gameplay. i.e. the above player founds Islam, and goes on to pursue trade and science with some vigour. After about 20 turns, you get a message from your domestic advisor telling you that your religion has acquired the 'Commercial' and 'Scholarly' traits-and ask whether or not you wish to adopt these traits (at the cost of 1 turn of anarchy). As with the previous case, every 20 turns or so, you might get a change in traits if you radically alter your gameplay style-but still at the cost of anarchy. Now, the important point is that any civ which adopts your religion gets the traits of that religion too. However, if you play against those traits, then you might find your cities becoming unhappy-and your relations with the religion's founder, and at risk of creating a new sect of that faith within your nation.
As you can see, we seriously avoid causing any offense whilst at the same time allowing for almost unlimited amounts of replay value, when you consider the total number of Trait+Trait+Religion combinations you can have. (i.e. consider 7 'mutually exclusive' traits and 7 religions. This would allow a minimum of 7*7*7 or 343 different combinations.)
