what he actually said was:
The only one I couldn't find any evidence of was holocaust denial. I had no clue who they were until B-a-S defamed Notch by calling him a liar. So I did a bit of reading and it didn't take long to find evidence of the 1st and 3rd allegation. I found plenty of holocaust denial within the labour party/supporters, but not attributed to the above named individuals. I didn't look hard. It may exist. Fortunately for B-a-S Notch's Identity is unknown, so he is protected by the Defamation Act 2013.
Still - not nice to wrongly accuse someone of being a liar, when its not true.
@JohnD - there you go - thats how its done properly. good effort.
