Christianity is inherently a community affair with the Body of Christ gathering to worship Christ and participate in the sacrament of The Lord's Supper. You cannot do that out in the World.
Another take on the subject is that if you, and millions like you, hadn't left The Church, it wouldn't be in the poor shape it is now.
If you, and those like you, didn't act like this in Church millions wouldn't have left. Maybe then it wouldn't be in the poor shape it's in.
Big +1.
I grew up going 3 times a week.
Last time I was in a church was for my grandmother's funeral several years ago. Prior to that was my dad's funeral, 16 years ago.
