I think love has no boundaries.

I know men who married Filipina bar girls who became great wives and good mothers.

Everyone can go down the wrong path and everyone has the right to make themselves a better person.

If someone knows they like a woman who is/was a "bar girl" she should tell the man out of respect for him.
He can then make a decision whether he wants to continue.

IMO, we should not judge people too severely, we may need the same kind of even-handedness one day
