lake Christians, do you think unwed mothers should be tolerated in church?

I ask this question because there is a woman in my church who is unmarried and obviously pregnant but she is just going about being a part of the church as usual. She sings on the choir and participates in activities and no one seems to be batting an eye, not even the Pastor. To make it worse, I have heard the father of her child is a married man. In my younger days a woman like that would have been kicked out of the church and I want to know how other Christians feel about this. I feel she sets a very bad example for younger girls and makes a mockery of everything the church is supposed to represent.there
