I appreciate that point of view, and recognise that I don't have a personal family connection to the Holocaust in the way that many do and might affect my emotional reaction to things, but I think that there can be value in comparing problems in contemporary politics to those found under the Nazis. There do seem to be some reoccurring patterns in the way people with mistreat others, and pointing to how some contemporary problems were also a part of the horrors of the Nazi regime can help prompt people to question similar behaviour today.
I don't agree with all of the Black Triangle Campaign's work, but think that they have done a lot of good stuff, and they were a group run by disabled people that was really ahead of the curve in pointing to the really harmful changes to UK disability policies. I learnt a lot from their articles, and their work encouraged me on to other further reading.
Any reference to the Nazis can back-fire, so I'd tend to avoid them out of caution, but at the same time I think it's still worth trying to push back against the notion some promote that any reference to the Nazis shows that the person speaking is an unreasonable extremist. I remember when Ministers tried to use a reference to Nazi medical examinations in the high profile Spartacus report (made only by the academic providing the introduction) to try to dismiss this work and avoiding meeting with the authors:

Since then the UN's CRPD found that the Government’s welfare cuts have resulted in “grave and systematic violations” of the rights of disabled people:

I find it hard to take seriously those who share some responsibility for these violations and abuses of peoples rights, and have failed to speak out about them, but then act affronted by any reference to the Nazis.
PS: When writing this I ended up looking at some general disability groups for references - wow, there are a lot of really intense expressions of hatred (and more) from those whose lives have been destroyed by politician's 'reforms'. I wonder if Sharpe would 'like' attempts to discredit the campaign disability rights by posting excerpts of them? David Jameson trying to discredit patients concerns about PACE by misrepresenting a couple of forum posts is pretty despicable.
