I think we agree on most of the points here - except for the great distinction that you seem to be reserving the right to ENFORCE your atheist/secular standards on other societies which have not yet (and in fact may never) naturally adopt them.
I didn't say anything about enforce (nice switch again, btw). We started with 'contamination' which led to 'structuring' and now 'enforcement'.
No. I say we keep talking, educating, sharing. Change comes from the inside. However, if we can take measures to immediately stop people from shooting young girls in the face for going to school, then yes, perhaps some enforcement might be in line---if it were possible. But I don't think it is, so let's continue contaminating until that is no longer okay in the eyes of many.
This is the Libertarian argument---that laws don't change hearts, so don't force people. Well I say that if it takes a law to make sure that a certain race can get employment at fair pay, then I don't expect that certain race to wait around for hearts to be changed---if there is a way around it. I don't think young girls should be patient as they get shot in the face, while waiting for hearts to change. We can certainly apply a certain amount of pressure that would not really be enforcement. We can construct things in such a way that allowing for human rights will benefit them more than not doing so. But we can't pass laws in their countries---this is no reason to give up all together.
