Dave Bautista is so furious over Roe V. Wade being overturned ... he's now begging men to get off their asses and speak up about women's rights, clearly believing it'll help avoid similar situations in the future.
"Every f**ing man needs to be louder about the rights of women," the former WWE champion said.
The "Guardians of the Galaxy" star made the urging at The Henry out in L.A. earlier this week ... just days after the U.S. Supreme Court reversed Roe V. Wade, the 50-year-old precedent that legalized abortion nationwide.
Bautista was very obviously still PO'ed over the decision ... and said flat-out that men should be doing and saying more to make sure women are not marginalized.
"[They should be] speaking out," he said. "Be f***ing loud."
