The 44-year-old "Charmed" star made the comment following reports Thursday that numerous actresses who would be attending the 75th Annual award show in January were planning on wearing black as a sign of solidarity in protest of things like gender inequalities in Hollywood and sexual harassment in the entertainment industry.
In addition to Streep, who has spoken out vocally against Weinstein despite working with him on August: Osage County and The Iron Lady, Jessica Chastain and Emma Stone are those who are said to be wearing black. "I despise your hypocrisy", she wrote on Twitter.
McGowan criticized the act as an empty gesture, accusing them on Saturday of remaining silent while they "happily worked" for disgraced producer Harvey Weinstein, whom she referred to as the "Pig Monster".
A sources said: "All female actresses attending the Globes are protesting by just wearing black gowns".
McGowan certainly did not mince words with her blunt attack on the women who will partake in the protest at the Golden Globes on January 7, 2018.
Streep, for her part, has issued no comment. "You gotta tune in, don't ya?" the 68-year-old told Extra.

"The disgraceful news about Harvey Weinstein has appalled those of us whose work he championed, and those whose good and worthy causes he supported".
Shortly after the Weinstein scandal broke, Streep had said that those who raised their voices after experiencing the alleged terrifying sexual abuse at the hands of the producer are "our heroes".
This month, McGowan turned on Streep after the latter actress characterized Weinstein's behavior as "the most gargantuan example of disrespect" across multiple industries dealing with similar accusations. "Each fearless voice that is raised, heard and credited by our watchdog media will ultimately change the game".
But, McGowan - who was one of the first women to come forward with rape allegations against Weinstein - is not impressed.
In a statement to ABC News, Weinstein denied any allegations of non-consensual sex.
