I'm having a hard time going through all the discussion on the most recent update, but there's a lot of discussion about the Rin/Molly interaction. Sorry if I tread ground someone else already has, for whatever reason I just couldn't keep reading the posts. Sorry.
I feel for Molly, and the scene was hard to watch, but there's more to Rin's reaction than just face value.
1) Rin is not in a good headspace for what's going on. Before she knows what Molly's going to do, she even tells her to hold off on the discussion until the night's events are done. She's terrified about what's going to happen between her and Otoha.
2) She clearly doesn't know how Molly feels about her until Molly starts acting desperate, and starts getting forceful. Molly's behaviour, while understandably having just been her finally breaking after all this has been coming to a head for a while, is also the kind of sexual harassment that gets people in serious trouble, and she wasn't stopping.
3) The two had just had a fight from Rin's perspective, and she's likely still mad at Molly. It's hard to shift gears.
Between these two facts, I think people are judging Rin too harshly. I think under different circumstances, and with less insisting on kissing, and aggressiveness on Molly's part, Rin would've been much gentler about things. As it is, there are signs near the end of the interaction of her softening, despite suggesting some time apart.
I think Molly is awesome. I want her to feel loved, and be happy. I know that the way she acted was out of an extreme emotional state, but her actions were also extreme, and between what Rin was facing later that night, and that fact - I'm not sure expecting more of her is reasonable.
