The point was more that the Beer Hall Putch failed, but was "forgiven" in the interests of "unity". Hitler and most of the conspirators were pardoned. The Nazi party ended up being emboldened instead of shunned or prosecuted. And the next time they were smarter about things.

This kind of rhetoric minimizing the attack at the capitol seems very much of a piece with the way the Bavarian establishment treated Nazism in the 20's to my eyes.
