Sometimes I post without thinking, mostly because the thread doesn't really require much thinking. But I really become hesitant in posting my opinions and views because I have a totally different paradigms than most members here. For instance, I not into same-sex marraige(really broad and controversial topic), but I do not openly say it to the public. Learned my lesson.
Well... I'm not hesitant to post my opinions if they're on something I know a lot about. If I can back up my opinions and be assured that there will be less of an upsetting argument and more of an interesting exchange, then I'm much more confident in posting my opinions. But I don't know a lot about many things, so I just scroll threads and leave them alone.
I'm mainly thinking of D&D here, but I suppose it applies to all sorts of sections that I end up wandering through. I mainly keep to myself and what I know because it's more fun for me that way. I don't like being all serious and getting into arguments. And I don't like being called out on my ignorance either, so I've just ended up not putting my thoughts out there. Aaaand this is beginning to apply less to PC and more to my general life, but you know. I do behave the same way everywhere really.
