Yeah I don't think I've ever heard anyone call Stan Lee a bigot. He's usually accused of stealing all of the credit for the characters he created by those who worked for him. I've been a Marvel reader for years, and I don't know anyone who would really claim he was a bigot.

That's more of Walt Diseny's shtick and even he has many defenders who worked for him that state he really wasn't, or at least no more racist than was socially acceptable for his time frame.
