It's more than that.
Consider that some people have been fans of the Chantry since the beginning. To have it all explode and just get reformed by anyone is sad. It makes the person who actually gave a damn feel worthless. That no matter how much you care, you're the same as the person who doesn't. One's personal investment or efforts meant nothing.. you're the same hero either way.
Yet it doesn't have to be, you have a choice, you can play a Human and rebuild it exactly as it was. Other people having a choice to tear it down while playing an Elf, Qunari or Dwarf won't affect your Human playthrough beyond a feeling of self importance and entitlement.
I can understand being frustrated at things that don't fit or feel right, the Human noble background with an older character being a prime example, it feels wrong for me as well, as such I don't play it. Does it mean I spend all my time complaining to those that enjoy a young PC that it doesn't fit the canon I want, no, I find something else that will fit for me and I can enjoy.
The way you are acting at times is that of a LOTR fan going onto a GOT fan forum, complaining that the paper the book was printed on could of been used for a copy of LOTR, that it was wasted having GOT printed on it. You are going out of your way to create an issue. LOTR or GOT or both is all personal opinion and rather than discussing merits or flaws of each, you just come across bitter that there wasn't another copy of LOTR floating about.
You're thoughts and opinions are very much valid to yourself and others, but venting them here doesn't add anything constructive to the topic people come here to discuss and enjoy and merely serves to derail the enjoyment others seek here.
