@eclipse suggested that all discussion of Bride Sanaki and the controversy surrounding her should be moved to here, so here I am.
As for my own two cents, I'm just shocked at how controversial the whole situation is. I believe this is the largest controversy surrounding a single unit the game has ever had (outmatching even Ayragate) and a lot of toxicity has been thrown around on both sides. As for where I stand, I don't exactly approve of it for the reasons stated in the locked thread by several people, but I also feel that the backlash is almost completely unjustified, as the seasonal banners are supposed to be all about heroes in cosplay.
Another thing worth noting is how we are pretty much playing out Sanaki's character arc: (FE9/FE10 spoilers in the textbox)
Anyway, I hope that people's thoughts on the issue can be discussed in a civil manner.
