Was the holocaust a hoax

In War the first casualty is- Truth! both sides of any major conflict aim for morale reasons, to show the enemy in the worst possible light. There are many unanswered questions about the Holocaust. even the promoters tend to avoid anything resembling a Veterans memorial tablet- albeit this is different than normal war death rolls. It seems very hard to swallow that about 6.7 Million Jews alone were killed by the Holocaust- there is very rarely any attempt to break this down statistically among the various prison camps. One might hasten to add there are too many survivors- and their stories conflict- Both sides have their stories- Certainly it happened- and on a Gross Scale- But- we cannot ignore factual distortions.
