I’m sure she’s well aware why they believe that to be the case. Most folks who come to the evolutionary creation position from within an Evangelical context understand the YEC approach all too well. I have little doubt that the OP has already carefully weighed various kinds of evidence for YEC and found it wanting.
So in my opinion it wouldn’t be wise or fair for her to open herself up to a one-way conversation where the other person tries, in a close-minded fashion, to convince her that she’s wrong. She would be absolutely right to shut out those voices. She’s right to seek out voices that encourage her to press in to her relationship with Christ. And if she’s in error, there will be those who have earned the right through their loving encouragement to broach those topics with her in love. Sounds to me like the folks she mentioned in her post aren’t in that category.
Turn the tables for a moment, Wookin. Do you enjoy it when Jehovah’s Witnesses show up at your door and try to convince you you’re not saved and need to come down to the Kingdom Hall? What about the aggressive Islamist who, every time they talk to you, want to extol the virtues of the Holy Qur’an? Well, maybe you enjoy a spirited debate with these folks. But for most of us, we don’t enjoy being told we’re wrong. We’d rather focus our energies on growing in the Lord. And that’s what I would continue to encourage the OP to do.
