1. Kurt was forced to keep the secret about the assault and Karofsky's sexual orientation because Karofsky threatened his fucking life. Or did everyone just conviently forget that little detail? Because that was the original reason why he didn't say anything eventhough he was terrified and telling about the sexual assault would have enabled Kurt to stay at McKinley and get Karofksy expelled.

2. You're right. It might not be forcing, but it sure as hell was coercive. Crying in the freaking hallway about how sorry he was for abusing Kurt doesn't really give Kurt much of a choice. Doing that in the first place was extremely selfish and Kurt would have been made to feel guilty and like a total ass if he didn't accept the apology.
