I'd recommend re-reading it, then, rather than asking questions that have already been answered.
They haven't been answered.
If the Creators aren't traditional gods - with the All-Father, Elgar'nan, cited as the son of the Sun and the land, for example, and responsible for the existence of the stars due to his battle with the Sun - then the Dalish faith in the Creators is wrong.
You keep harping on that - over and over and over again.
BUT AT NO POINT HAVE YOU DEMONSTRATED THAT ANY OF THAT IS PART OF MODERN DALISH BELIEF.
Do you really think that many people today believe all the stories about Zeus, Aphrodite, Poseidon, et. al.?
Which requires that we ignore the moments in Trespasser where the Creators are said to be "elven mages" and "false gods".
You continue to assume that anything a character says is supposed to be taken at face value - even though I've pointed out some specific examples where they were wrong.
They are threatened because the Chantry outlawed their religion - it's also cited as the reason why the ancestors of the city elves were forced to convert, as I already stated. We also have Clan Sabrae mention in Act III that Andrastian humans threatened with them violence in attempts to force them to convert to the Andrastian faith.
Which humans were those?
And what do you suppose this conversion actually involves? We've actually seen in-game other Dalish elves move to the city w/out giving up their beliefs. Do you suppose they aren't permitted to tattoo their faces?
Given how their religion is criminalized by the Chantry, your comment doesn't make any sense. And that's not even factoring the existence of free mages among the Dalish.
You keep saying it's criminalized, yet show no evidence of anyone ever being arrested or prosecuted for it. Your saying it does not make it so.
You've yet to demonstrate how alienage elves are prevented from practicing any non-Andrastian faith. In spite of your insistence that you know so much about Dalish belief, you've never offered any information about just exactly what their practices are. Do they pray? Meditate? Sacrifice virgins at an altar? Is the consumption of fish forbidden during a full moon? Do they hold hands and sing kum ba ya every morning?
What exactly is it that they're not being allowed to do?
The Tree of the People isn't a deity to the City elves. The vhenadahl is a symbol of Arlathan to the City elves.
Correct. Yet, according to Sera, elves "pray at" the vhenadahl. What do you suppose that means?
Perhaps, instead of trying to argue that the Dalish don't actually believe in their own religion, you can simply concede that you were wrong?
Perhaps, instead of trying to argue that you know exactly what the Dalish believe, you can simply concede that you might be be mistaken?
