I would suggest that striking up conversations with complete strangers who had previously demonstrated no interest in the case is slightly more obsessive than joining in an already established online conversation on the matter. I think your behaviour is odd, and as you have no problem with Amaral publicly criticizing and blaming others, nor should you have a problem when you are the subject of such criticism- imo.
Well since 'the complete strangers' were enthusiastic participants in the conversation I started I think I'll take my social cues from them rather than likes of yourself who did not witness subtleties such as body language, eye contact, tone of voice etc.
I think your behavior here in the main leaves a lot to be desired eg referring to other posters as obsessed/odd. GA publicly criticizing others has nothing to do with members here treating others with respect. If we allowed members to go around accusing other members of being obsessive and odd posting would descend into name calling.
It seems to me you want to be divisive and sow discord because you have formed the view you can do so and get away with it.
