No, I don't agree. Hitler wasn't the only Nazi - there were others, early on who were very socialist and interested in an ideal utopian, nationalist form of socialism. Some of them saw Hitler as selling out when he became more prominent.
The trouble is Hitler is such a bogeyman (obviously, and understandably of course) that people get hysterical when these comparisons are drawn. It's not offensive. It's a comparison, but people can't cope with that and immediately start flinging accusations that you are calling someone Hitler etc.
Look at what HappyCria actually wrote:
"Someone on dh's Facebook feed has gone on a big long lecturing rant to try and educate everyone on the similarities between hitlers rise to power and the snp's tonight.
Dh finds it funny at his ignorance
( - let's belittle and laugh at the person who sees a historical pattern, and call them ignorant when in fact it's the opposite - they happen to be aware of some history - )
but I'm feeling quite hurt insulted that someone honestly believes that people that want independence are no different to those that supported the nazi party!!
Now, the person on facebook apparently did not say that at all. They were talking about some similarities in the rise to power - in other words, in the early days of the Nazis, when Hitler was gaining power, there were some similarities with the SNP - namely Nationalism, Socialism, and a surge of patriotic feeling.
But that is turned into "people that want independence are no different to those that supported the nazi party!!"
That is a HUGE leap, a false one, and has then been used as a reason to take offence.
The same comparison has been made about UKIP's agenda, and reasonable so. I think it's a good point to make, because it raises the point that nationalism, though not necessarily inherently a bad thing, can turn very unpleasant and get hijacked by some very nasty movements. I don't like or trust nationalism for exactly these reasons.
