Sounds pretty simple and explicit to the rest of us.  The example is dress, but the principles are all the same.  You state that EGW spoke to men and women, she did.  Just because some do not hear or listen does not create a false proposition, no different than in "The Scriptures are plain upon the relations and rights of men and women". 

You mention the prime and perpetuating cause.

"How wide the difference between those schools taught by the prophets of God and our modern institutions of learning! How few schools are to be found that are not governed by the maxims and customs of the world! There is a deplorable lack of proper restraint and judicious discipline. The existing ignorance of God's word among a people professedly Christian is alarming. Superficial talk, mere sentimentalism, passes for instruction in morals and religion."   PP P594

Is this your light for HIM to others; or something else?  Maybe customs of the world?
