Hey,

Removing a record involved in a Many-to-Many relation will automatically also remove the record from the join table but will not affect the other object, so it's not really comparable to a Many-to-One relation.

This is not so odd: in the posts-tags example? Why would you want a tag to be deleted when one deletes a post or vice versa? But it is of course natural that the relation between a post and tag is removed if one removes a post or tag.

Regards,

koen
