1. Sorry, but that's how I see it used probably 99% of the time. Are you a native English speaker? And does it sound right to you to say "It's unethical to THINK X?" It sounds completely wrong to me, and (typically) when I bring it up to a native English speaker, they almost always think about it and agree. Maybe you missed that memo, but it IS the typical usage, as I've observed it and confirmed with others. You don't have to believe me, but I've gotten a surprising number of upvotes (here and elsewhere) as a result of posting about this topic, so I think I'm not being crazy here. 2. This actually follows trivially from #1, in that ANY thought crime (looking at porn, coveting, thinking disrespectful thoughts of an elder, etc.) is de facto NOT about a relationship, and therefore can't be "unethical." You may not believe #1, and if not, well, your loss. Not interested in arguing about it further. But you shouldn't be confused as to how #1 can imply #2. There's additional confusion from the fact that "Ethics" as a topic of study is often just a synonym for "Morality," (capital letters) which doesn't take into account the colloquial meanings of "ethical" (lowercase 'e') and "moral". tl;dr: English actually sucks.
