Therefore your observation that 'there was a lot more activity back then' is nostalgia pandering or a love for seeing content-less thread crowding.
Uncharitable interpretations, ho! You don't really have any justification for such claims but go ahead and put more words in my mouth. Oh, I see that you did.
If you can't click two buttons to join the temp debater group and wait less than 24 hours to post, then I think that we have a different take on the word 'interest' as excerpted from, '... I can't just jump in on a topic when I see one that interests me.'
The Proving Grounds and the Debate Hall are not exactly the same, are they? If the thread of interest is in the Debate Hall, then no, I cannot jump in after a mere 24 hours.
Also, the use of the phrase "jump in" does not imply anything about the level of thought put into my posts. It is referring to my relation to the conversation, i.e. that I'm joining into a conversation that was taking place between strangers. I suppose if I were more like you, I would've said "interject" for the sake of using a less common word.
Debates shouldn't be knee-jerk free gun em' ups between two ignorant parties because that easily devolves into insults and has no educative value.
What does that have to do with anything I said?
Nothing I said could be construed to mean that I think debates should be that way.
Debates are intrinsically meaningless and the word internet debate itself suffices as an insult attributing to how easily discussions can fall apart into drivel, especially when they involve intellectually vacuous subjects like religion.
Debates are intrinsically meaningless? Not only is this a ridiculous statement that you contradict but one sentence later, it also is irrelevant.
While I'm an atheist, I don't think that debates about religion are necessarily intellectually vacuous either.
The value-gain from a debate come when facts are put on the table because objectivity is cross-applicable to numerous subjective opinions whereas subjective opinions do not have the same versatility and importance outside of your own brain and in the hands of someone else trying to make a valid argument.
Cool story bro. Your unnecessarily convoluted wording of what is actually a pretty trivial observation does not impress me. It just demonstrates that you are a poor writer or purposefully obfuscatory.
If you don't want to put in the time and effort to get into the Proving Ground then you shouldn't bother, they are likely too pretentious to enjoy the high quality unrestricted opinions you have inside that brain of yours.

If you're representative of the population of the sub-forum, I will agree that they are too pretentious. I am skeptical that everyone in there could be as pretentious as this though.
But I will be nice and help you be less pretentious. Here are some pointers so that your use of big words will be good for more than just overawing the illiterate.
"Ration" refers to an allotment, it does not refer to simply a proportion. A high proportion of the posts were given to religious topics, not a high ration.
"Educational" is the normal word. "Educative" is synonymous and does not provide you any greater clarity. I assume your only purpose in choosing it was to sound smarter by using a less common word. However, it just sounds pretentious.
Nitpicky, but "internet debate" is a phrase, not a word.
I don't think that "suffice" is the best word for what you mean there either. "Suffice" means it is adequate for that. I don't think you meant that "internet debate" is adequate for being an insult, but that it has such a poor reputation that it is commonly recognized as one.
Your use of "attribute" is even more off the mark. "Attribute" is a transitive verb concerning thought, which means it needs a subject capable of cognition and a direct object. Your use of it lacks
both a thinking subject and a direct object. I think "attributable to" is probably what you intended. But you probably should've just stuck to a simple and clear word or phrase, like "due to".
I don't think you meant "reality" when you said "objectivity", and "objectivity" is not equivalent to "objective facts". The "cross" in "cross-applicable" is a meaningless flourish which adds nothing to the sentence which is not already obvious from the fact that you're applying it to "numerous subjective opinions".
Speaking of which, opinions are inherently subjective. It is redundant to say "subjective opinions" over and over unless your goal is simply to stuff more large words into your sentence.
I'm not really sure where you got the term "meritus", unless you simply meant "merits". Even so, I can't make sense of it. Perhaps you meant "if you don't think the exclusive club merits such exclusivity"?
Also, do you always give such baseless insults (indirect though they were) upon first meeting? Ironically while in the same post you are admonishing others for being supposedly too impatient to check facts and quick to post "personal opinion garbage". Apparently such admonitions do not apply to yourself or your evaluations of others.
