writing

That sounds like a good strategy resulting in you really understanding the "source material".. more so than just farming the responsibility out to a sensitivity reader. However, for those who are lazy and broke, another option is to do a beta swap with someone who's in the group you want a sensitivity read from. Maybe you can't be too lazy for this option though, because trading manuscript critiques is a fair amount of work. But it's a different kind of work than doing a bunch of research, so it might appeal more to certain writers. Just thought I'd mention it.
