Yeah, that does often times seem the attitude, and I can't imagine you could have a more damaging viewpoint of people. "The universe will shit all over you, there's absolutely nothing you can do about it. but at least it wasn't your fault". Literally can't think of a more damaging, disempowering sentiment.
That said, even if his justifications are shit, he is correct in implying that there is a point where you can become maladptively paranoid. Your interactions with people, I sincerely hope to God, typically don't end in sexual assault, and treating every person as if there is a more-likely-than-not chance that they'll assault you sexually will likely see you living a very reduced, unfulfilling life.
At the same time, as you said, pretending like it won't happen again (or that if it will happen, you won't have any control over it, as your lovely therapist implies) won't help either. You'll need to learn to balance the right amount of caution with the trust that the majority of those around you will not assault you sexually.
This idea is simple, but simple doesn't mean easy to apply. I imagine you could spend an entire lifetime refining ways to protect yourself from such scenarios.
For me personally (and I say this as someone that hasn't been sexually assaulted, God forbid, so grain of salt I guess), I would want to passively anticipate it. That is, I want to bolster my ability to react to such a situation, rather than trying to avoid it outright. Learning some kind of martial art, carrying a weapon, reaching a point mentally where 99% of the time I don't have to think about it because I'm confident enough that if the situation starts happening, I'll be both willing and able to defend myself. Perhaps that's just larping, though.
Whatever the case, I sincerely hope you can 'recover' so-to-speak from your experience. Oh, and I wouldn't recommend lying to your therapist, the world is a worse place when people aren't telling the truth. Just be straight with him, tell him that you find his worldview disempowering and masochistic, and that you'll be finding someone else, or just dropping out of therapy over all. (Lmao you don't have to read this verbatim, I'm probably projecting my own beef with him, but just something along those lines)
