I have the same problem when trying to tell people about Steemit, Hive or other crypto currencies. People seem to like their system, the one that causes them to lose day in and day out.
I helps to have "ears to hear", otherwise it "goes in one ear and out the other". The assumption is that what we have might not be great, but it's what we know and we get very good at complaining about it - having to learn about something completely new to complain about requires a lot of work.
"Behold, the people of Israel have not listened to me. How then shall Pharaoh listen to me, for I am of uncircumcised lips?"
If Moses compares an unskilled or ineffective body part (his lips) as "uncircumcised", I wonder how the people of his time esteemed other body parts that are uncircumcised.
