stoppingbywoods - I have to agree with LineyReborn about your misreading of my posts. Where have I said anything about insincerity, not caring, pretending to care or anything along those lines?
All I have pointed out is that the primary focus of the Operation Christmas Child scheme is evangelism.
I have no doubt that the people who are distributing the boxes and running the discipleship courses sincerely believe that finding Jesus is the best thing that could ever happen to anyone, and that by converting children away from Islam/Buddhism/Hinduism/other forms of christianity, they are saving them from Satan's grasp.
However, that is not exactly a universally held belief, and I do not think that is the kind of cause that British schools should be encouraging children to donate gifts to promote (and I do not think many of them would support it if they realised that was what was going on).
I would also take issue with your use of the term 'humanitarian' to describe OCC. Distributing gifts and running bible classes are not humanitarian activity, they are missionary work.
Humanitarian aid is about providing safety for people fleeing wars or natural disasters, or improving the lives of people living in poverty by giving them access to food, clean water, better housing, medical care, education etc. There are thousands of genuinely humanitarian charities out there doing precisely those things. Some of them have a Christian ethos, some do not, but the primary focus of their activities is providing the aid that people need, not converting them to a different religion.
For example, nowhere in Christian Aid's statement of values does it mention promoting Christianity - it is all about alleviating poverty. Cafod is similar. Samaritan's Purse, on the other hand, says it aims to "to earn the right to share the love of Jesus Christ through acts of kindness to people in need" - in other words, it believes that helping people gives them the right to evangelise to them.
I think many Christians would not find that acceptable, and Samaritan's Purse has come under frequent criticism for evangelising to people it is supposed to be helping, ]]www.nytimes.com/2001/03/05/world/us-aids-conversion-minded-quake-relief-in-el-salvador.html for example after the earthquake in El Salvador]] (they did similar things in Haiti after the earthquake there).
