Sarah Jessica Parker explains the one Twitter comment that made her blood boil

Early last month, Sarah Jessica Parker uncharacteristically lashed out at Twitter user “Sarah J. Symonds” who made a rude comment about the Sex and the City star’s twin daughters.

The Twitter user deleted her original message when SJP responded, making the specific comment a bit of a mystery by the time media picked up on it. However, based on the wrath it inspired, the message was obviously quite insulting…

Your anonymity doesn't diminish your outrageous and vulgar tweet. And your deletion only reveals your cowardice. @SarahJSymonds

I'm certain there isn't a woman on this planet who would support your specific kind of cruelty. No apology, no explanation. @SarahJSymonds

You should be ashamed @SarahJSymonds. I hope more people join me in voicing their objection to and holding accountable… (cont)

…uninformed and unkind women like yourself who find pleasure and delight in attacking other women. @SarahJSymonds

SJP wrapped her rant by thanking fans who came to her defense, saying she didn’t “relish the opportunity to publicly reprimand,” but felt the woman’s false allegations needed correction.

So, what exactly got the shoe maven so fired up? Speaking to The Edit, SJP explained she was angered when the woman questioned the parentage of her twin daughters, Marion and Tabitha. She said she was nothing but honest about the fact the girls were carried by a surrogate — but are biologically her and husband Matthew Broderick’s kids.

“That particular day, it was just one of the things I saw. I kept scrolling and then I was like, ‘Wait a minute, did she just say that?’ I went back and I thought, ‘Well, this isn’t unhealthy paranoia, this is absolutely conscious. This was a choice.’ She, not subtly at all, said that my children are not my children,” SJP explained. “I don’t want to encourage people picking on her, because that’s no better. But I wrote back, ‘What? Like, is this fun?’ She never responded and deleted it.”

She added that, throughout her career, she’s taken great care to never come across as “self-centric.” Because of that, she couldn’t understand why the woman felt the need to throw such a low-blow.

“I can’t figure out what she hated so much about me that she did that. And I just can’t imagine anything lower than that,” SJP said. “Would she say that to my husband? I can’t stand [it] when women say unfriendly things to other women. Why does it have to be like that? Why do we go from [I disagree with you] to I hate you, I attack you, I use words that I know are hurtful? And we’ve never met! You’d think at this point in my life I would be accustomed [to it], but we keep finding new ways of expressing ourselves, new outlets to be unfriendly and cruel.”

Now that some time has passed and cooler heads have prevailed, SJP just wants one thing from the Twitter user…

“I would love to hear from her. I would just like to understand.”
