Unfortunately the evils perpetrated by Hitler have many parallels. The human race has committed many acts of evil and extermination often along genetic lines. We owe the few victims who are still alive almost 80 years later our sympathy and our commitment to prevent future evil but we do not owe them our silence. These events are like it or not part of our common historical context.

I absolutely would accuse someone of color of imitating a slave,r if the shoe fits wear it. I have never been afraid to step on toes and I don't think society should fear to give offense if it gets in the way of honest discussion. Contrary to your assertion I think discussion keeps the events of the holocaust top of mind and relevant. Too many already deny it even happened.

Also complaints about getting downvoted attract downvotes.

On the primary topic of discussion do be aware that a Israeli terrorist detector might misidentify both Jewish people and Palestinians but who do you think would be subject to additional scrutiny or mistreatment? Such tools run the risk of attaching seemingly scientific justifications to our pre existing prejudices.
