I was not moderating that thread, but reading through it, the directive seems pretty clear: do not post further in that thread off topic your opinions on whether or not they should be missionarying. If you want to discuss your thoughts on that topic, start a new thread.
You decided to continue to post, anyways (regardless of reason--others mentioning your posts being your excuse in this case). You got a warning for that, and seemed to take enough umbrage to start this thread. That's fine.
I don't see the issue though, seems pretty clear, to me.
If you don't like the other people's comments on your thoughts, feel free to PM them, or, again, address it in your own new thread.
Let me be clear: you do not have an unequivocal right to post in someone else's thread.
If a moderator asks you to stop, please stop. If you have an issue with that, start a thread about it. Don't * in their thread.
Cheers!
