Question

The villagers are normally simple poeple Can we rewrite this sentence removing the article the before villagers Would this change the meaning more or less ?

Answer 1

Yes, it can be written as villagers are  normally simple people.
It would change the meaning as 'the villagers refers to villagers from a particular village and just villagers refers to people from all villages 

Answer 2

yes , if we write without 'the' , it would change the meaning of the sentence.
the villagers are normally simple people means that the people of a particular village are simple.
villagers are normally simple people means that all the villagers of this world are usually simple people.
