You are not addressing the scenario. If the other aircraft had TCAS, then you'd be painting him. In the given situation, you are not, but ATC is. He doesn't have TCAS, ergo he has no RA nor (as far as you know) does he even know you're there.

Right into where he might well be?
You may well not want to manoeuvre against the RA, but then it also appears that you don't want to try to avoid the unpainted intruder at all. Your choice, but it wouldn't be mine!
