I guarantee you a generic anime community is on average a lot more pro-arranged-marriage (and pro-child-marriage, pro-slavery, etc.) than this forum
I do remember Reddit being very pro "just marry some guy and take the girl you love as a mistress" during MagiRevo. It took until they literally showed Anis throwing up from having to go through that, that the voices finally quieted down and people realize that no, forcing her to go through that arranged marriage was maybe not a good thing.
And Dynasty... is the same. Mind you, it's not like Anis was physically coerced - she just had such a monumental pressure from her family and position, that there was no room for choice left. It was the same in Sheep Princess, and it's the same here; they don't have a sword on their neck, but arguments that they're "free to choose" are tenuous. In fact, Sheep Princess showed the girl crying, and here we see Makino being very uncomfortable, so it was already shown that they're not fine with this situation, much like Anis.
But you can still see people defending the part in which they are setting up marriage interviews. The saving grace is that the parents are homophobes, which makes them designated villains, so people won't defend them; despite defending other parent characters doing the same thing in other works.
It would be interesting to see what the comment section would look like if the parents weren't homophobes, but equal in every other way. Probably a battlefield. Although I don't really mind the author intentionally villainizing the parents behind this coerced marriage, just to make sure it is very clear that you're not supposed to approve them because of "cultural practices".
I would have expected that Dynasty criticized scenarios in which a girl is forced to marry someone other than her lover under coercion (and to recognize that "Marry that guy, or we'll throw you in a dungeon / in the streets with nowhere to go" is, indeed, coercion). Instead, I saw the dominating reaction being... barely at the level of Reddit anime communities. Yeah, that's a low bar.
