Putting aside the obvious non sequitur in Gae's post (comparison does not imply causal link after all), here's some overview:
https://en.wikipedia.org/wiki/Hinduism_and_Judaism
All good and dandy, except note that some (if not most or all) of these prominent "scholars" have profiles like this:
Steven Rosen (quoted in the OP btw) is editor of the magazine for the Hare Krishna movement:
https://en.wikipedia.org/wiki/Steven_J._Rosen
Clearly not trying to promote their religion at all.
For "scholar", we also have a Hindu mystic by the name of Rajneesh:
https://en.wikipedia.org/wiki/Rajneesh
We do have at least three scholars mentioned/cited that seem legit:
Constantine Samuel Rafinesque was said to be a genius thinker but it's not clear if he had relevant expertise on this topic being discussed and if he even made comparisons between Abraham and Brahma.
Hananya Goodman who is author of "Between Jerusalem and Benares: Comparative Studies in Judaism and Hinduism", supposedly representing "the first serious attempt by a group of eminent scholars of Judaic and Indian studies to take seriously the cross-cultural resonances among the Judaic and Hindu traditions." However, access to this work has been difficult online, so withholding judgement on this one.
Then there's David Flusser, who is quoted as saying that "One can easily discover parallels in the Upanishads to the Abraham legend" but a look at this article (which I have been fortunate enough to find online) shows he wasn't comparing Abraham himself to Brahma, but rather a specific legend about Abraham to what was said in the Upanishads.
