It all comes down to chemistry and expectations. Engineering types generally appreciate candor, a somewhat unique trait, but it's definitely gaining some traction with other groups. I don't think many investors appreciate it, but that doesn't mean a cold email won't work -- but it better be extraordinary.
Actually, I don't consider "asking someone back to their place right away" as either positive or negative thing because I don't understand the motives. Sorry, this kind of interpersonal stuff simply goes beyond me. ;/ But I assume that if that is important to someone, I don't see a reason for that person not to be candid about it.

It's more that I see no reason for why this should matter when many business people don't even consider the effects that their actions or decisions have on human communities, changing the lives of countless other people. So many of them don't give a shit about what difference it makes when they decide to do something, but when someone else deals with them, many of them dwell on superficial veneer rather than on substantial matters proposed? Sounds very much like hypocrisy to me.
Being candid about something usually isn't the best way to accomplish your goal. If your goal is to make a sale, and you communicate with them in a way that is too different than what they're used to, you simply won't hear back. Forget ever getting a sale if they won't even talk to you. Understanding how people perceive your communications, and using that to your advantage is an important life skill.
