A Banned Wedding

All right this is just weird and inappropriate. Imagine this: Girl goes to seminary in Israel, calls up her wealthy dad and tells him that she's found this incredible boy and wants to marry him. Father goes into a fit of rage because this isn't the type of boy he wants his daughter to marry, and goes on a rampage to break them up.
I'm not going to get into whether what the couple is doing or not, that's between them, but what really disgusted me was the reaction of the Charadim.
Now I try not to judge fellow Jews (except regarding Aliyah issues) but this really threw me. Maybe I'm not understanding the subtle nuances of what's going on, but the fact that this is going on should not be public knowledge. This should have been settled privatly between the families, they shouldn't have gone to Rabbi's who would post posters all over Mea Shearim telling people that this is wrong.
How is what they're doing wrong first of all? Let's say that they both are committed to Torah & Mizvot and want to build a strong Jewish household together, why should anyone want to stop them? There's no evidence in the article (after all it's Ynet, promoting liberal, secular values) that they are not planning to do this, and if they were going to "go off the derech" together it should have been settled privately. I don't think this is the case however, they could easily have had the wedding outside of Mea Shearim, but the fact that there are people outside protesting, waving signs, like the Netirei Karta do when they're protesting Israel, is frankly rather insulting.
Let's say this blows over, and the father accepts this. How do you think the kids are going to be treated. Knowing some of the things that are taught in some of these schools regarding tolerance, these kids are going to have to walk around with the label of a Mamzer.
This is, unfortunetly a sign of the times that we as the Jewish people are forgetting the core values of the Torah. Bait Hillel said that the Torah could be summed up with "Love your neighbor as yourself," and that's one of the core things that is missing from the Jewish people right now.
