Occupy Wall Street was 2011.

I took Google Ngrams with some various terms around social justice, set smoothing to 0, and sorted the outcomes. Feel free to verify; I'm no expert.

Tested terms (alphabetical order): Bigot, Bisexual, Black, Cisgender, Civil Rights, Critical Race Theory, Discrimination, Diversity, Empowerment, Equality, Equity, Gay, Gentrification, Hate Speech, Heterosexual, Homosexual, HRT, Human Rights, Identity Politics, Inclusive, Inequality, Intersectionality, Lesbian, LGBT, Liberation, Marginalize, Microaggression, Oppression, Privilege, Racism, Representation, Social Justice, Solidarity, Systemic, Transgender

I certainly didn't sort them perfectly. I don't want to tell you what to think, but I will say that I was pretty sure of this theory before running this test, and though I feel the evidence supports it, it wasn't as strong as I thought.
