Offering to sell a domain name is not per se bad faith. If the domain name was registered because you knew it was a trademark, and the value you are seeking to derive from selling the domain name derives from its value as a trademark, then, yes, you are trying to make a buck off of someone's trademark. The text on the page is immaterial. It really depends on the name.
Now if you have reserved the domain name for future use but you are willing to sell it, that's fine. But if you simply registered the domain name because you want to sell it, then I don't see where being a liar makes you look any "better" to anyone. In fact, it makes you look worse.
Personally, I think "domain name for sale" pages are a dumb idea anyway. If someone wants to buy a domain name which is registered, they are perfectly capable of looking at the whois data and making an offer. I don't have a "for sale" sign on my car, but if someone wanted to buy it, I'd listen to what they wanted to offer. That's the way the world works. If you have enough money to offer, you can buy my left leg, but I don't walk around with a "for sale" sign on it.
In the meantime, by posting a "for sale" page, you are missing out on any opportunity there may be to capitalize on whatever traffic the domain name might get. What's the point of that?
Looking at one case where there was no response, and making some general conclusion for all possible domain name is also pointless. There are plenty of UDRP decisions involving speculators who were selling generic words as domain names, and for the most part these cases are won by the respondent if they bother to file a credible response. Similarly, there are also cases where respondents have curious ideas about what constitutes a "generic" name, and were unable to produce any black and white evidence of their specious "future plans".
So, if I understand you, the question is "Will lying about my intent in registering the domain name help me?"
That's a no-brainer.
