I referred to a particular point in the original cite[0], which is unsourced. Taking that to refer to my entire argument is, well, bad faith.
As for your new cite, I'd say it's the arguments in favour that are most damning. They tend to eventually concede the point that G&S did not and would not ban the behaviour leading to the crisis; They just lament that their policy choices weren't implemented at the time or lament some 'cultural shift' with no evidence to substantiate it (IMHO, everyone looking could have seen the culture shifting at least a decade earlier).
Aside, the argument was never that regulations are never repealed - but that the natural overall direction is ever expanding regulation. This thread is arguably somewhat of a confirmation, since people are arguing for a regulation which had little to do with the crisis...
[0] "The perception is that the Glass-Steagall Act created a sense of accountability among investors within the financial management industry... Thus a cultural shift was certainly in order after its repeal regardless of the loopholes that existed prior."
This has no source, and violates wiki's ban on original research.
