Surely they taught you the difference between fiction and non-fiction, right? A feel-good speech is just that.
The theory is that if it walks like a duck, has feathers like a duck, and quacks like a duck, well, it probably is a duck. The frats and sororities were/are a hotbed of problems on our campus (and we only have 8 total). (Not the one I attended but the one I work at off and on, in the counseling center) It is nice, though that you personally didn't have such problems.
OP- I'm glad your daughter is happy, even though we see this differently. (you might not send your daughter off to France like I have either!) Oftentimes, the pledges aren't allowed to talk about their experiences, and you might want to make sure she knows that it is ok to talk to you or someone on the campus (counseling center, etc.) if something happens that doesn't feel safe to her.
