Would you resubmit? A good rejection is perplexin.

I received a "good rejection" yesterday from a short story market notorious for their high standards, and long response time. Relevant portion of the rejection is below. In light of the points raised (which are very helpful and ones that I'm fixing) would you fix and resubmit the story, or not risk the etiquette breach because there is no explicit invitation to do so?

Here is part of the email:

"We held this for consideration longer than most stories, because it's well-written and enjoyable, but much of the dialogue seems there for the benefit of the reader rather than the characters. I wanted to be more torn up about [Character Name]'s supposed death, and more overjoyed when it turned out she was alive; when we discussed the story, I found I wasn't the only one. I would like to note, however, that we appreciated that the romance did feel realistic, and I personally appreciated the inclusion of lesbians who aren't fighting against societal discrimination, but instead the Capulet/Montague trope. It's always nice to see science fiction manage to progress past where we are now and simultaneously portray eternal human issues. Anyway, though this one isn't for us, I wish you the best of luck placing it elsewhere, and I hope you'll send us more of your stories in the future."
