Should ALL Holocaust museums have to provide 'evidence' of Holocuast?

Jews do not have to supply evidence. If they did then their would be ONLY a Jew/ Russia holocaust, seeing as how Stalin slaughtered twelve times the amount that Hitler supposedly did..... I don't know what happened to the Britain/ Boer holocaust ?. Or the Spanish holocaust?....About the same numbers and the same concentration camps, the same amounts of executions, but all quietly booted into the long grass..........Obviously holocausts only happen when Jews are the victims. Answer to your question YES...The evidence that Hitler was responsible for the holocaust should be presented.....All be it impossible to present since surely Stalin was the man responsible for the REAL holocaust.
