Thirdly, why is that no matter what I do, or what results I get my HATERS always have to resort to "Sinny got lucky, Sinny just OMGUSs everyone" "Sinny obviously got help" "Sinny was pivvy to information we wasn't"
I think you might take things a bit too personal. For people new to mafia, obviously it's going to seem completely weird/ baffling you zoned in on two right scum from the start. New players don't know about tells and signs and to them it's like seeing magic, while the magician knows it's just a trick
If you don't understand the reactions, it's partly because outsiders can't see the leaps in your intuition. What you tell us you see doesn't always seem more convincing than what other say they see. If things were so easy, mafia games probably wouldn't be so popular. Some of what makes mafia appealing is people can't trust their own or others judgments.
Maybe it's different for you, I'm just trying to explain where others might come from. It's not because people don't think you're able, it's because they find it weird for even able people to pull that off. To me how you write also comes off as more "chaotic" which makes it more difficult to follow your train of thought. So to me what you wrote initially didn't come off as common sense or obvious.
Which is probably because of the way we think is just in a bit of contrast. And I think that's a good thing, because if everyone was an INTP in every mafia game, I think it would be a bit boring. Better to have different people with different ways of thinking.
It might annoy you that others don't get you and your logic straight away, but I don't think much can be done of that, except give it time. And with it, some will get you and some just never will. I think most people experience other people not getting them, some just experience it more than others
