Then why don't you ever complain about Bhelen practically changing dwarven society and pretty much being the correct option?
Also, how about the fact that a dwarf becomes the ruler of an entire marcher city state or the fact that an elf, dwarf, or qunari can become a comte despite how radical a non-human gaining a noble title is.
Thing is, he doesn't. Aside from the fact that, as I recall them - it has been a while, admittedly - the ending slides made Bhelen's reforms out to be more of a struggle than they did with Leliana's, twelve years later in DAI, there's no real indication that his struggles have taken effect. I recall there being some threads back not long after release mentioning war table missions that show the situation in Orzammar is still pretty much the same.
I may need to look it up, but I do I remember because I specifically called out the fact that if they had Leliana's reforms from the main game stick when they didn't with Bhelen's would cement Leli as a sue for me, and here we are.
As for the Kirkwall stuff, let's break that down. Firstly, Kirkwall is one tiny city state, not three fourths of a continent. Secondly, we never really see any anti-dwarf racism in Kirkwall in the seven years we spent in that town; the Dwarven Merchant's guild is apparently a big power player there, owning a district in High Town, and Varric is a native son as well as a nobleman, and he committed serious resources to it's restoration. So, yeah, him being made Viscount, especially when it's established that no one else wants the job? Not a huge deal, anywhere near on the level of Leliana's over all reforms to the chantry.
As for the comte thing, again, minor title in a small city state, and one we get no real follow up on to see how that plays out. It's also something I don't imagine we'll ever get any real follow up on, like how the Warden could become Tyern of Gwaren. Just one of those things that's going to be quietly swept under the rug and left to our imagination.
