Several years ago, I was the victim of mob mentality twice within a year.
The first incident came when I won the award for this book, the leader of the mob was a person(?) who had pilloried me online for months - despite it being against the site rules - in the end, she had to admit I am a better writer than she is, I beat her in a Facebook writing contest - I did not want to enter - beating her in a contest that she had no control over must have stung her ego. I can't say as I left the site months before the contest; I did think of rejoining the site just to see her reaction, but that isn't my way.
The other incident occurred at a writers club here in Bristol, this is the only time I had given a public reading since leaving college in the 70s', and I wish I'd not joined the club. The incident came after I did a reading from my bestselling e-book (Forgestriker), a week later, a person in the club started a witch hunt because I re-posted a Facebook against dog-fighting; he assumed I was part of the paramilitary group posting the original post.
Because he ran the club, I was tried by a kangaroo court in absentia; that is what annoyed the most, nobody asked me for an explanation because the group leader had spoken out against me.
I am not surprised at the actions, or the results, some people cannot accept I am a better writer than they are, I am surprised at how the actions were undertaken if you have an issue with my let's talk it out, not go behind my back and undermine my work as valueless.
