Jesus, Brenda, you don't half talk some bollocks.

1. The internet isn't a primary source for anything. Research done on the internet is pretty much sloppy by definition.
2. Typing in "Baby Boomer" or "roaring 20s" into the Google Images search box isn't a "sloppy search", unless you're some kind of idiot.
3. You're still being a lazy arse, despite your post hoc rationalisations of your lazy arsiness.
