What is the point in posting a thread attacking someone else's system of belief? Rather than making the thread about MAYAVADIS and how they are so bad and incorrect, why not just speak about what VAISHNAVAS believe about Vaikuntha. There really is no need to bring in mayavadis at all, especially not as the main title of the thread.

It would be similar to a shaivite starting a thread called "Hare Krishna's are idiots. They think Vishnu is God."

Just present your belief system, and don't get into the evils of everyone else's belief system. When the title of your thread is about another belief system you are inviting them to come and criticize you here. If the thread was named something more appropriate like "The Glories of Vaikuntha" then the mayavadis wouldn't bother reading your thread and you could peacefully discuss what ever it is you wanted to discuss. But when you title things like this you are just provoking others to come and argue with you.

If any "mayavadi" made a thread about Hare Krishna beliefs, all the hare krishna followers would complain to ban the "offensive" person. So please be considerate of other's feelings and beliefs. If you are really trying to convince or convert people to your belief system, then speak in a way that is attractive to all people.
