What it's boiling down to is the decision of Rose Quartz to 'bubble' Bismuth without confiding in the other Crystal Gems as to what happened to her, as well as not to use Bismuth's weapon 'the breaking point'. A lot of the fans are going with the line, "It was a war... and if the Crystal Gems were captured, chances are that they would be shattered. why is it wrong for them to shatter other gems in their fight?" Which is a very classic way of seeing an intense conflict on this scale. People die in wars, it's what happens.
I like this conversation between fans, because it's challenging many of the classic notions of how things were done. It's making people question and wonder why things have to be the way they've always been. Why do people have to be killed because we disagree? It may not be a stance that we can realistically reach in even our lifetime, but it's good thought to consider before we (as a species) are quick to pick up a gun and seek conflict. Steven isn't perfect, but he's shown to have this strong moral center that guides the Crystal Gems. He's ready for conflict if it happens, but that's not his first choice to resolve a problem. He protects, but he wants to resolve situations through understanding and communication. Yes, it's idealistic... but it's a cartoon about trying to always do the right thing.
The other issue that came up was Rose Quartz lying about what happened to Bismuth. This was the more difficult choice, and one that by the end of the episode we see Steven go for the choice that was more honest. At the time the conflict between Bismuth and Rose Quartz happened, they were in the midst of frequent clashes with the Homeworld Gems. They were always outnumbered. Bismuth was clearly a popular gem among the Crystal Gems, energetic and charismatic. If Rose Quartz had a split with Bismuth, it could prove to split their group in half at a time when they were barely keeping the other forces at bay. It would have meant the end of the rebellion as the two smaller camps were individually overwhelmed. It was a morally gray problem, and there are plenty of people who can say "Rose did the best she could". However, Steven shows a maturity beyond his years by risking his connection with the other gems and telling them precisely what happened. And though the moment is glossed over, it's obvious that this choice hurts and is still accepted by the other Crystal Gems. That's the difference of Steven... he is willing to take a risk and communicate, where as Rose had her secrets.
As an added little hint, there was a discussion between Bismuth and Pearl when they talked about how they were always outnumbered and Bismuth mentions to Pearl about the time Pearl took on the ship of Nephrites. One really sharp fan caught that, and brought up an image of nephrite as a stone... it's a sort of darker green, sometimes with darker speckles or bands. Which looks a lot like the colors of Centipeetle, who captained a ship. Bismuth also mentions other Crystal Gems such as 'Crazy Lace', 'Biggs', and 'Snowflake'. Which likely refers to crazy lace agate, biggs jasper, and snowflake obsidian. While I'm sure we haven't seen snowflake obsidian, biggs jasper definitely could be the tan corrupted gem that Jasper captured in Gem Hunt. And while there were some stylistic choices, crazy lace agate has so many different appearances it could be the green and red other corrupted gem that Jasper captured. All in all, there was a lot packed into those two episodes!
