Group berates ogoni clean exercise

I think there may be a bit of a misunderstanding here!

It seems like you're trying to say that a group is criticizing or berating the Ogoni people for their exercise routine, which is focused on cleanliness. However, I'm not sure what "Ogoni clean exercise" refers to, as Ogoni is a ethnic group from Nigeria and I'm not aware of any specific exercise routine associated with them.

Could you please provide more context or clarify what you mean by "Ogoni clean exercise"? I'd be happy to help you understand the situation better and provide any assistance I can.
