It's like nobody here watched the video or took the time to understand what she said.
I watched it instead of simply assuming its content and she makes a good point. You should remain pure for your love of Christ who died for your sins on the cross and not for the promise of a husband, another fallen human being.
She's not advocating to "find yourself" and "lol it's ok you can winnie the pooh around God is gonna forgive you" she simply says that if you made a mistake don't winnie the pooh ruin your life into maximum sin mode because the church taught you that you were a bar of chocolate and once you get winnie the poohed you're ruined forever.
And that girl is a virgin (now married) so it's not like she felt personaly attacked as people claim.
That being said,
1)men prefer debt-free virgins without tatoos for good reasons
2)Be careful of "born again sluts", I've done shitty things in life and I know people can change so I'm willing to forgive and all, but be careful, nature isn't easily changed
3)Some girls might get her message wrongly and believe that fornication is "just another sin, I'm a christian for God and he's gonna forgive me anyway" (this is really perverse thinking, I've experienced it before)
TL;DR : You guys (and the woman who wrote the article) are right, but the girl in the video ain't wrong either.
