NEW YORK (CBSNewYork) — Actress Olivia Wilde is pregnant, fed up, and taking a stand about the lack of courtesy on the subway.

As CBS2’s Alice Gainer reported, a very pregnant Wilde issued a very angry tweet on Wednesday afternoon.

Many on Twitter were quick to support Wilde.

Many others were quick to attack.

Signs are mounted on subway cars for the Metropolitan Transportation Authority’s Courtesy Counts campaign encourage people to offer their seats to those who are elderly, disabled or pregnant.

CBS2 followed a noticeably pregnant Natalie Polanco on the train to see if anyone would give up their seat for her.

Most people had their heads down as CBS2 watched Polanco stand as the subway car left the station.

Kim Oscarson, in her third trimester, said once she started showing, people started getting up.

“I haven’t had any issues,” said Oscarson, of Floral Park, Long Island. “People are very respectful, actually.”

Both women made an interesting observation about who typically gives up their seat for them.”

“Almost every single time someone has given up their seat for me, it’s been a woman,” Polanco said.

“Mostly women getting up though for me over men,” Oscarson added. “Men seem to want to turn their head and act like I’m not there.”

And what do the non-pregnant subway riders observe?

“Some people often do, but some people don’t, but my mother is pregnant,” said Miralva Quiroc. “That’s the reason I do it, because I think of her.”

“We’re pretty much kind New Yorkers, so we pretty much show compassion and consideration for those of us who are pregnant or whatever,” said Russell Holloway of Budd Lake, New Jersey.

And if others give up their seats, maybe Wilde’s next tweet will be a “thank you” instead.
