The enshrinement of victim culture is something that has always kind of existed in societies, but it has taken a very malicious turn in the modern world. This phenomenon was/still is (ironically) used to bring about conditions favourable to the rise of totalitarist governments. Hell, both fascism and specially communism rose up from victim culture.
The very basis of Marxism is victim culture. Hell, Marx himself can be seen as the ultimate SJW stereotype, as he himself was a very rich and privileged college rat who leeched off his friend and never worked or owned a company in his entire life, and would've never been affected by anything concerning working class people, and yet he managed to distort his image to the point that he became seen as some sort of savior of the proletariat, through the magic of victim culture. This in turn would allow for one of the most terrible totalitarian regimes in history to come about.
It can be still seen today as a shady electoral/political tactic. A political figure latches on to a minority or dissatisfied group and then continously feeds their resentment towards the majority, making sure to further separate them from what is considered "mainstream" society. He then starts influencing intellectuals in universities, which quickly creates a significant group of impressionable but influent young minds who will then spread his ideas to the younger generation. Over time, you create a society in which a large chunk of it is dedicated to those ideas, and anything that is not in favor of these ideas is seen as injustice, opressive and whatever other evil adjectives you can tack on it. Combine this with political propaganda and you have yourself quite a basis for the rise of a new political order that can basically do anything it wants, even things that it supposedly condemns, since it can easily justify it as "for the cause" and being against the supposed evil, opressive majority, instead of the suffering minority it claims to represent. This behavior is rewarded by the group in question once it starts to gain political leverate, by attempting to create legal advantages and benefits for people of the minority groups it claims to represent, under the guise of social justice. This goes on for some years.
Some time later, insults and construction of stereotypes become acceptable against anything that does not conform to said group's ideas. Once the group rises to power, it starts to slowly push out any opposition, eventualy using censure and other underhanded means. With a few more years, you got yourself a de facto dictatorship going on, under the guise of a "benevolent ruler" from the oh so great political party that does everything it can to claim that it represents the intentions and rights of the poor, opressed people. Once it has enough power over society, it'll even go as far as to rewrite history books, painting every government before the current one as some sort of saturday morning cartoon villain, and the current government/ruler as a messianic savior figure.
Thus, you have Venezuela, Bolivia, North Korea, Soviet Union, and many others. I know this argument is kind of a huge slippery slope, but this is something people need to be aware of at all times, and why you should be wary of any government that likes to be large and in charge under the guise of representing the poor/opressed/etc.
