I'm sure the "oh well, you were stupid enough to trust an exchange so you deserve to loose your money, now on with bitcoin for those of us that didn't loose our btc" atitude has something to do with a major segment of would-be BTC promoters keeping quite and moving on with their lives.
That would be fine for a mature BTC economy but anyone that thinks that is where BTC is yet has more learning to do than those that lost their money on MtGox.
