Invite learned Speakers

Sir,
This has reference to many  festivals like Vishwa Karma Day  that are celebrated in honour of various religious deities. Many organisations hold religious discourses to enlighten the masses about significance of these days. But at times the people who sermonise do not themselves know much about such events.
It is requested to all such organisations to invite only those who are learned and do not hurt the religious sentiments of people by their lack of knowledge.
Yours etc….
