"Not having Altar Girls is a problem for some people. For me, the mother of girls, I see nothing wrong with it."
As a father of three boys and two girls, I see plenty wrong with it. In fact, the text that follows your quote from above answers correctly what you pose. My family (and many others I know, all with many girls in their families) refuses to attend Masses where altar girls flit around the sanctuary, ESPECIALLY when they reach puberty and beyond. It is a distraction, and one that is being made especially to adolescent males.
Anyway, this is the official document on "allowing" female altar servers.

1) Canon 230 #2 has a permissive and not a preceptive character: "Laici . . . possunt." Hence the permission given in this regard by some Bishops can in no way be considered as binding on other Bishops. In fact, it is the competence of each Bishop, in his diocese, after hearing the opinion of the Episcopal Conference, to make a prudential judgment on what to do, with a view to the ordered development of liturgical life in his own diocese.
2) The Holy See respects the decision adopted by certain Bishops for specific local reasons on the basis of the provisions of Canon 230 2. AT THE SAME TIME, HOWEVER, THE HOLY SEE WISHES TO RECALL THAT IT WILL ALWAYS BE VERY APPROPRIATE TO FOLLOW THE NOBLE TRADITION OF HAVING BOYS SERVE AT THE ALTAR. AS IS WELL KNOWN, THIS HAS LED TO A REASSURING DEVELOPMENT OF PRIESTLY VOCATIONS. Thus the obligation to support such groups of altar boys will always continue.

I'm sorry, I did not state my position clearly.
I should have said that while some people have problems with excluding girls from serving on the Altar, I have no problem with it.
I have Choir Girls. That is fine with me and my girls. Boys should be serving on the Altar.
