I'm nominally Christian (sent to sunday school when a child for years, but not Christened), I have some very Christian friends, even a vicar or two, who'd I'd consider good friends. I don't think that there is anything wrong with individual Christians, any more than any other person, and a certain type of, young, come as an adult to Christianity Christian, tends to be so very nice, helpful and generally the kind of neighbour you want.
However
As in any organization there is also a type of person who seems to be there more for the glory, and those are the people who put me off going to church as a child, when, because my parents weren't church-goers, my siblings and I were regularly snubbed (despite the highest attendance at sunday school, being eager to help, and really not bad children), in favour of the children of people in the church committees.
and in general principle, organised religions (or people in the name of religion) perpetrate atrocities, both small and large, world-wide. Sexism, homophobia, mutilation, gross misconduct with charitable funds (you only get our money if you teach abstinence etc.). You may say that it's only some people, and it's not really Christian to do these things, and yet it's written into church law that women can't be bishops etc.
