A no lynch is only useful in exceptional circumstances (like 4 left, 1 mafia alive etc). Lynching a non-contributing user is always better than a no lynch. If you were to not lynch, all the discussions and infornation gathered in the day go to waste, as you cannot draw any conclusions from it. This helps the mafia more than town as they are the informed group while town aren't.
Moreover, the chances of getting a power role lynched is 4/17 (counting the lovers though I shouldn't as they really have no power) right now which is lower than that of getting a mafia of 5/17.
Also, I'd suspicious of anyone claiming as vanillager. If you were a vanillager, you have nothing to do, so you might as well sacrifice yourself for the greater good. Not to mention, that by claiming vanillager you increase the chances for the mafia to figure out who the inspector/bg are as it now increases from 2/12 to 2/11. So, it more probable that whoever claiming vanillager are mafia and looking for a "safe" claim. And since a lynch is always better I'll

His dislike of any lynch does not go well with me. Combined with the fact that he said that lynching a power role is same as that of lynching a mafia (which it isn't) and that if a power role is randed and is forced to claim, then he can be protected by the bodyguard, so its not a freekill for the mafia.
