That's alright if you have no firm beliefs of your own.
So you're saying that having firm beliefs of your own means you shouldn't take what others have to say seriously? I disagree. If we respect others, we should I believe take what others have to say seriously. Having firm beliefs and taking what others have to say seriously are not mutually exclusive.
I didn't say anything about questioning, though, again, if you want to actually learn, you'd be better off listening and reading and talking little. It isn't wise to make all your questions publicly known.
I believe we can learn from many different sources. And I don't see any problem with making one's questions publicly known.

In the process of questioning things and arguing for particular positions one can strengthen those positions or alternatively rethink one's stance on particular issues. That is all good.
Why not read a book on the topic, listen to a lecture on the topic or go through the articles on the topic?
One can do all those things and also explore things on forums.
