I've seen and participated in many "back and forths" (reasonings) on forums. Yes, things can get heated at times and some folks seem to have the need to be perceived as "right" but don't let that stop you from posting your opinion. I've learned lots on the many forums and have further explored the topics brought up in order to form my own opinion. So, yes, go ahead and post your opinions and let them resonate with whom they may!
