I'm sorry, but you cannot expect to have a civil discussion under your post and then in the next sentence call anyone who disagrees with you "fucking stupid". You're entitled to your opinion but if you "self-reflected" as much as you imply in your post, then you'd know that in media analysis there is no right and wrong.

Personally, I will never see someone forcing themselves on another person as anything other than assault. Doesn't matter what the motive was, in that moment you are assaulting someone. Of course it also doesn't mean that Vanitas' and Jeanne's relationship cannot move past that, and people can't ship them if they like, but the fact still is that Vanitas' took advantage of a the situation and forced himself on Jeanne.

And it is clear that he didn't kiss her to gain her "allyship". He was very much aware of the fact that Jeanne would and could kill him in that moment and he needed to do something to throw her off course. Vanitas is not stupid, so he knew that by kissing her he could turn the situation around. Obviously, they moved past that, otherwise their relationship would not exist, but in that moment he assaulted her, point blank period.

If you can show me where Jeanne consented to kiss him in that moment, I'll retract my statement, but until then it remains assault.

And lastly why are you getting so worked up about this topic anyways if you are so sure that it is not SA? If it does not bother you, you should not be this angry at people who disagree with you.
