It is entirely possible to think someone has been dangerous in the past, and to also think that person has reformed and is unlikely to behave dangerously again in the future. If it weren't, then every crime should carry a life sentence since reformation is impossible in your worldview.
His posts are relatively to the point, there aren't any randomly capitalized words, and he has gone more than 2 posts without throwing out any childish insults. He's obviously an alt, but I don't think it's CH/TOAA on this occasion.
