OK. Can you clarify since it is a hot button issue? I mean, I was hoping to get some input on how exactly what Blackwall did was not, in fact, rape by deception.
From the source you linked: Rape by deception is a crime in which the perpetrator has the victim's sexual consent and compliance, but gains it through deception or fraudulent statements or actions.
He explicitly says that he wants you to end it with him before there's a chance for anything more to happen than the flirting between you that has gone on prior to your first major decision. In no way does he lead the Inquisitor on for the purposes of tricking her into having consensual sex with him like those cases cited in that wiki.
It's the total opposite of that, but if you want to go reading that into their relationship, well, what's anyone going to do? I find it semi-ridiculous, sorry. I read the linked article about Richard Allen Minsky, and let me say that what happens with Blackwall doesn't sound even remotely similar to this particular situation or to the other situations described.
It's on the player for initiating the relationship and for refusing to let it drop when he asks you to end it, and that's all there is to it as far as I'm concerned. *shrug*
