GH – While everything you wrote may very well be true, it in no way disproves the assertion that college has a negative affect on a girl’s Ruchniyus.
Before you posted, Joe had not written that college was worse for girls than for boys. He simply stated that college is bad for girls, which is true (although it doesn’t necessarily follow that no girls should attend college).
In any case, why are we making a comparison? Whether it’s worse for girls or for boys, the fact is that it’s bad for both and is something that should be avoided if possible.
Of course, there are many factors to consider, and if someone does feel that she must marry a guy who is learning, while she should still try to avoid college if possible, that is not a realistic option for everyone.
Not everyone can be a teacher or Ganenet, so some girls may need to go to college if they want to support their husbands in Kollel. And there are Rabbanim who give heteirim for girls to go to college in certain cases, although I think that all Rabbanim would agree that it is a b’dieved and if one can avoid it, she/he should.
