I don't want to defend gulags but they didn't have poison shower rooms or child corpse disposal staff.

Neither did concentration camps:

"Interned persons may be held in prisons or in facilities known as internment camps (also known as concentration camps). The term concentration camp originates from the Spanish–Cuban Ten Years' War when Spanish forces detained Cuban civilians in camps in order to more easily combat guerrilla forces. Over the following decades the British during the Second Boer War and the Americans during the Philippine–American War also used concentration camps.

The term "concentration camp" and "internment camp" are used to refer to a variety of systems that greatly differ in their severity, mortality rate, and architecture; their defining characteristic is that inmates are held outside the rule of law. Extermination camps or death camps, whose primary purpose is killing, are also imprecisely referred to as "concentration camps"."

Don't minimize the Holocaust on your way to agree with everyone else that tankies are delusional assholes.

The singularity of the Holocaust lies in the extermination camps, where millions of people were murdered with industrial efficiency:

Saying that concentration camps exist(ed) in other countries is not Holocaust relativism.
