Yes when he said
it seemed quite clear that he wanted to discuss that. But then...
Key phrase in bold. Now it's not so clear anymore. So what does he want to discuss? A conspiracy theory? Or the moral issues of providing pills that interfere with your biology?
Well lets test that theory.
For the sake of conversation lets say Yeshua wanted to discuss A) conspiracy theory surrounding the pill
and B) moral issue of issuing the pill. Quote me all the posts that reply to that.
I need to point out beforehand that simply mentioning the pill doesn't make it on-topic, it needs to reply to either point A or B. So "the pill is great!" or "when my girl takes the pill she can't get pregnant hihi" do not apply.
I think you'll find that the only person who was on-topic was vg4030. Only he "contribute[d] positively to the conversation". Not saying I have a problem with most of the posts there, it's not their fault the thread was unclear and they simply looked at the title (which is not the way a thread works).
As for your police analogy, even though you said it's a weird example it still doesn't apply. I didn't arrest him for wearing a pink shirt, I arrested him for wearing a pillowcase with 2 holes and trying to pass it off as a shirt. It wasn't a
bad thread, it was
no thread (remember the definition of a thread, it's more than just a topic title).
I still feel I was right on closing that particular thread and I haven't seen a single argument that proves me wrong but I think you're more interested (rightfully so) in discussing the closing of threads in general so go for that. I've personally never seen a problem with the way threads are closed so I might stay out of that discussion.
By the way, I didn't take any offense to the whole pointing fingers thing. I just feel that whenever I was an admin/super mod/mod I've always been fair and open to criticism so I'll never let someone say I've abused my powers, even online
