I replied to your comment on Spirit's not possessing people or crossing the Veil.. If you knew they have, why on earth did you say they don't?
I said they do not concern themselves with crossing between the planes (whereas "demons" are), nor with possessing people, because they don't. Justice was forced out of the Fade against his will, and it was a mutual decision to merge with Anders.
Wynne was possessed against her will, once again I will ask you to get informed on your lore before making comments on the matter 
Given that Wynne had the ability to eject the Spirit and even controls the amount of power she draws from it, the spirit most certainly does not inhabit her body against her will. This type of interaction would also preclude it from being possession in a literal sense.
I would also like to ask you to point out where i stated spirits will start possessing people en masse because of the breach. If you're going to continue to totally take my posts out of context, don't bother replying..
Because I'm giving you the benefit of the doubt by assuming this somehow links back to the original question of whether or not the Breach should correlate with a surge in abominations... as opposed to just making irrelevant comments for the sake of being pedantic.
I also have no reason to 'try again' as you so politely put it, read the Codex, get a bit of knowledge on the subject and all will be clear. I find it funny you're trying to argue against canon lore and in-game explanations written to answer questions such as yours o.O
Yes, I am aware of what the (in-universe perspective) codex says. Of course, it has nothing to do with whether or not demons prefer possession as opposed to manifesting in their pure form via weakened veil or rift. Neither does it discuss the issue of demons choosing to possess people when they have already manifested in the mortal plane. You're just name-dropping a codex for whatever reason, even though it doesn't hold any relevant information pertaining to this subject.
