Until I read this thread I was seriously considering not attending LonCon (despite budget meaning it would be my only event this year). I now feel that the explosion of bile that has filled my computer recently is just a symptom of twitter and the like, not truly representative of fandom.
I had truly reached the point where I felt that as a WASP male I was no longer welcome (the white, anglo-saxon, male is an accident of birth, the protestant is by choice). Now at least I know that a reasonable number of fans will judge me by the actions and decisions I make and not, as seemed to be happening in the twitter-storm, as at personal fault for every transgression of every WASP male in history.
Thank you all again for restoring my faith in fandom.
