A believing friend of mine shared this video about a river near where we lived in our youth. A dam was blown up to clear the way for the free flow of the stream and the return of the salmon.
It wasn’t difficult to see the relation with Freethought!
What dams need to be blown to open up the free flow of ideas?

Believers are the dammed. It’s a pretty neat trick to assure someone they have arrived when they haven’t.
Indeed, Jim, many minds are dammed. We need more dismantling of the brain blocks.
