Do you all think that the new C/A forum was so difficult to find by accident? And that all the main opponents against Calvinism have their threads closed or buried in a separate forum while the Calvinists threads are permitted in the general forums? Oh but of course the Westminster Confession is allowed to be discussed because its about a creed and confession but not about Calvinism, even though one poster specifically labeled the contention over the creed an issue about Calvinism TWICE in the very opening paragraph. Even many Calvinists had noticed this and spoke up about it.
The fact that this hypocritical standard is not only being applied but supported by many Calvinists shows a gross willingness to use deceptive and deceitful means to promote their ideology so long as the ends justify the means and that speaks VOLUMES about their character.
I am not a Calvinist.
But I can speak to some of your complaints.
The discussion of a Confession or Creed whether Calvinist or not, is not about Calvinism. It is about Confessions. If a poster takes that thread off the topic of confessions and turns it into Calvinistic doctrine, then he is in the wrong for derailing the thread.
What if the thread was about the Catholic Catechism? Would it be about the "Catechism" or the discussion of Calvinism? Or even the discussion of "Purgatory"? One cannot derail the thread by taking the discussion away from the topic of "Catechism, Creed, Confession, etc." and start railing on any specific doctrine. They are in the wrong. Stick to the topic at hand. Make sure your posts are directed to the OP.
If a thread is closed it is often because the poster's have gotten out of control. Read the rules. Post in grace, respectively, taking into consideration others. Love your neighbor as yourself.
This may be a debate forum, but it is not necessary to be an embarrassment to all the world that is reading it. I or any other moderator shouldn't have to come here and edit half the posts, or do which is much easier--just close the thread. That is the primary reason threads get closed--not because they are Calvinistic or non-Calvinistic, but because the language being used is over the top, disrespectful, antagonistic, offensive, insulting, etc. It need not to be that way.
Post in grace. If the rules are not clear then please read them again.
