I think the problem of talking about the "holocaust" is that people tend to conflate some terms. I likely suspect some parties do this out of a strict bias.
In this case, when people say "holocaust", they tend to mean "systematic and purposeful elimination of people with a Jewish ethnicity". Which is often conflated with "oppression of the jews", "jews dying while in interment", and "jews dying at all".
So from most direct to most indirect, we have a sort of acending level of maliciousness. From least to most:
1. Jews never died from anything even war-time related
2. Jews dying at all
3. Jews dying while in interment
4. Jews dying from direct or overt oppression
5. Jews dying from an attempt at systematic extermination
I think the problem is when people try to go away from the facts we have from history, and head towards whatever position they are bias towards. In this case, I often seem nazi apologist try to imply a 1 or 2, which is clearly not historically accurate. But then mainstream media (and society in general) tries to push 5, of which there is startling little evidence for (and most of the evidence directly contradicts this).
Just something I think about.
