Matt Garza, a Major League Baseball pitcher for the Milwaukee Brewers, recently took it upon himself to weigh in on women’s health care.

On Jan. 12, actress Jessica Chastain tweeted her disappointment in the Senate’s recent vote to gut the Affordable Care Act, which could force millions of women to pay for birth control out of pocket.

“ # BirthControl is no longer covered by health insurance,” Chastain tweeted. “Congrats USA, you’re doing your part to keep women out of the work force.”

If you are not ready to provide for a family, if you want to finish school, if you want to build a career, protect yourself. #IUD @PPact — Jessica Chastain (@jes_chastain) January 13, 2017

A little over an hour later, Garza, who from what we can tell does not know Chastain personally, responded to Chastain’s tweet.

“It’s called abstinence, a word that has been forgotten amongst this generation,” the 33-year-old tweeted. “It’s the best contraceptive... #juatsaying [sic].”

Although abstinence is indeed a contraceptive method, it is one of the least popular, with the most popular method being the birth control pill, according to the Guttmacher Institute. Research has shown that when funding is cut for women’s health services, sex education and contraceptives, people don’t abstain from having sex ― they simply have less safe sex.

As many pointed out on Twitter, Garza, a man, is perhaps not the best spokesperson for what women should do with their bodies. Twitter users quickly joined in the conversation in Garza’s mentions:

.@Gdeuceswild Yeahhh. How many ppl do you know who are abstinent? Don't lecture women about abstinence...especially when you had a kid at 18 — Nick Bolton (@NickBolton13) January 13, 2017

@NickBolton13 @Gdeuceswild He also forgets the fact not every woman wants kids, so we're are supposed to be practice abstinence FOR EVER? — Brittny Pierre 🎈 (@sleep2dream) January 13, 2017

@amiehartnett Tons of men literally have no idea how their wives prevent pregnancy, I suspect — Susan Calvin (@FakeSusanCalvin) January 13, 2017

The next day, Chastain tweeted that she will be attending the Women’s March on Washington on Saturday, Jan. 21.

“I am marching to protect the disenfranchised,” the actress tweeted. “I stand with you for reproductive choice, wage equality, and freedom from sexual violence.”
