You don't have a problem with his behavior? The 10 years ago argument doesn't work either because that would make him a man in his 40's saying the things he said, not a naive teen. This also occurred over years, not just a single lapse in poor judgement. Very creepy, very offensive. He was given a second chance working with Warner Brothers. There is not a single reason I can buy into that would find his return to Disney acceptable.
The first elementary google search for his remarks:
Nearly two-dozen tweets were unearthed in Guardians of the Galaxy director James Gunn's Twitter feed this week.

It is not even remotely funny, and no matter what angle I look at it, I cannot defend him.
