Replying to Threads getting deleted

Not my threads, but it seems like many more threads are getting deleted for no apparent reason. The Phil Robertson/Duck Dynasty thread, Poon_Hammers ridiculously hilarious thread, and theres been a few others. So what gives? If almost every user wants to see it, and it isn't spam, why is shit getting deleted? Because its offensive?

Big ups to the mod's, you guys make the site tick, but it would be nice to have a bit more consistency on what is deleteable and banable and what isn't.
