The video shows the woman approaching members of Abort67, who are stationed outside Blackfriars Medical Practice- a GP surgery offering abortion services in Southwark- with a video camera and explicit posters of foetuses.
Confronting the protesters, she says: 'You are wrong in what you're doing.
'You don't know why people are doing what they're doing, but you want to be out here judging and then filming.'
When one of the female protesters fights back by claiming she had an abortion in the past and regrets it, the pregnant passer-by labels her a hypocrite.
'You had an abortion but because you're not happy with what you're doing, you're standing out here making other people feel guilty. When you had an abortion, that was your choice,' she hits back.
'Many people have been abused you don't know what their reasons are for, so I think this is so wrong on so many levels.'
Referring to a recent incident in which a newborn baby was found dead in a wheelie bin, she adds:
'There was a baby on the news that got found in the bin.
'Maybe if their mum didn't feel that way because of people like you, that baby wouldn't have died.
'You think it's better for them to get rid of it at ten weeks (in the womb) or to actually go through with the birth and then kill the child?'
Finishing her argument, the woman continues:
'There's Kids Company round there, where we're helping thousands and thousands of kids while you're out here.
'You get raped by soldiers and then tell me what you would do after that.
'You are in the wrong place, especially when we have our people that are going through their s*** , they're going to Kids Company where we're meant to help them, then they see this.'
She adds: 'To be standing out here and making other people feel guilty is so wrong.'
The protesters are left with no comeback and the video ends.
Campaign group Abort67 was founded in 2008, and travels to UK clinics confronting women with posters and leaflets featuring pictures of foetuses.
A spokesman for the group told MailOnline:
'The YouTube video by Sunny Hundal which reveals the gentle nature by which we hold our displays serves to emphasise that abortion is indefensible.
'Pro-aborts like Sunny can’t defend killing small human beings so he tries (in vain) to shame our volunteers for trying to defend the unborn child.'
