You are right, playing 1♦ was never my expectation when I chose pass. (i know you did not reply me but still..)
I was quite certain that was not your primary motivation.
Others mentioned it though, and I thought it deserved to be addressed.

Over 1♦--1♥--2♥ we know we will never let opponents play in their 8 card suit at 2 level. Even if we are one of those who are conservative, not letting them play 2♥ when you have a 6-4 shape and decent values is obvious I hope.
You double 2♥ and can find a 4-4 ♠ fit easily if there is one. If not you can correct 3♣ to 3♦. So with the example auction you came up with, let alone feeling uncomfortable, I would just feel as if I hit the jackpot!
If your partnership is clear that 3D there is this sort of a hand, then you may indeed be better off with a pass - there are a few sequences where you may be able to get your hand type across later in the auction. My broader point (which I know you don't need to be told) is that the decision about taking action or not on the first round isn't just about that point in the auction. The real question to be asked before choosing is how we'll be placed after likely continuations, and whether passing or bidding will help us.
I still think an initial 1NT overcall will lead to a better score on average, but I generally prefer initial aggressive action rather than entering later. IMO, tramticket pretty much nailed it with the first response on the thread.
