I have read this person's grievances concerning Dark Shadows Fandom and believe this person had been injured from his personal experience... of which everyone would agree is unfortunate... although I also believe the only avenue for him, in my opinion is for him to face those who caused him his pain to begin with and not air anyone's soiled linen so to speak in a public or private forum.
I, as a enthusiast of Dark Shadows have limited experience with said fandom, I am, I suppose very fortunate in that everyone I have met during a Dark Shadows festival have been kind, caring, intelligent individuals with a normal liking for DS, they have real lives, they are real people, I respect every one of them.
I do not know how others may perceive this person, I do however believe I shall treat him with great caution.
