I don't have an issue with folks raising their hands and holding hands in Church during the Our Father. It is something that has popped up it seems organically and has spread throughout the Church in America. It isn't going to go away, and don't really see a reason for it to do so. You don't like holding hands then don't. It is as simple as that.
The biggest issue in my opinion is the obvious loss of reverence for the Blessed Sacrament that I'm seeing everywhere now. It growing like a wildfire. When I first joint the Church 20 years ago, everyone kneeled in Mass, when it was called to do so. When anyone approached the altar they kneeled and genuflected. Before they went into pews, same thing. Now in so many churches kneeling is no longer a practice, or it is only done during the Eucharistic Prayer. People who approach the altar if they do anything might nod their heads or do a slight bow. Not many even do that anymore when entering the pews. Its getting so bad that some parishes don't even have kneelers any longer. The Church I visited in Cincinnati, this past weekend, had nothing. Everyone stood when the Missal calls for kneeling. This is a horrible shame, and for folks visiting for the first time, it gives no indication that there is Someone very important in that building.
