What were the contents of the meme sent by Oluo's coworker that upset her and sparked an online altercation?

In Chapter 2: What is Racism?, Oluo describes spending four hours engaged in an online altercation with one of her coworkers. The woman had sent out a meme implying that welfare benefits should be tied to negative drug tests. As a person who grew up in poverty and knows what it is like to try to survive day to day, Oluo is offended by the implication that poor people are irresponsible, addicted to drugs, and just looking for charity so that they can spend their days engaged in using various substances.
