The Church is what it is.  Are you familiar with the seven sacraments, one of them being marriage?  Yeah, perhaps that's why the Church is so obsessed with people getting married.

Any other sacraments that you think the Church should emphasize less so that young single people will stop by mass once in awhile?

The Church is under attack by secularists and radicals; has been for much of its history.  So should it self-destruct by cowering to its detractors or stand firm and continue Jesus' mission for it?  It's hard for young people to be faithful to the Catholic Church when there is so much pressure from government and well-healed interests pummeling them with propaganda.  That's trouble for the youth, not the Church.
