Yorubas, Educated or not can't speak proper English, right?

Even though you are so much educated, you still can't construct proper grammar. Referring culture to religion, lol. Very funny. That's a shame.

As to the greetings, I agree with you about taking it for "respect" and that's the culture and you should respect it. Sincerely, you've gone beyond the boundary. I should be learning something new here, but I ended up wasting my time.

One thing is, if you can't respect others, don't expect it in return.

May God help you.
