I’m 35 and have known about the allegations since I was a teenager. The allegations predate the internet and were already rife at the time of Wood’s death in 1981.
KD’s own autobiography is pretty disgusting. There’s a disturbing passage about him having sex with a woman he suspected of being an anti Semite (seemingly because she was wearing a crucifix 
). When he climaxed he yelled at her.
Here is some of it in his own words;
“When it came to sex, Douglas admits he looked at it as if he were on a big game safari in Africa.
“I looked at something and BANG! I had total control. I enjoyed [killing]; the Masai gave me a shield and a spear and called me Killer Douglas.”
In fact, he said he once used sex to punish a woman he knew was an anti-Semite.
He said he took the woman to bed, keeping the fact he was Jewish a secret until the climatic moment, when he screamed:
“I am a Jew! You are being f— by a Jew!”
Even taking the Woods allegations out of it, he had a pretty horrible attitude towards women and sex.
