If King's Landing hadn't been hoarding Wildfire in those children's hospitals, the collateral damage would have been much lower, but you fire tactical long range arrows into sovereign territory like Cersi did and you will be met with a proportionate response - unless you dragon-hating leftists are going to seriously argue that Daenerys isn't entitled to defend herself. It's hardly Daenerys' fault that so many people in King's Landing were brainwashed by Cersi into getting in the way of that dragon, but then they don't value life like we do and they see dying as an acceptable cost to making the only legitimate democracy in Westeros look bad.
