Has reading a post ever facilitated a change of mind surrounding something of significance?

I have been reading and posting on different forums for years. There is never a shortage of individuals willing to explain their opinion or position on most any given topic. Lots of people are quite adamant and very passionate about their point of view. And many posters are quite articulate, well informed and rather convincing. So I’m just wondering if anyone has every changed their mind because of something they read on a forum. Has some well articulated argument ever convinced you that you should re-evaluate a previously firmly held belief? I’m not suggesting we are wasting our breath either way. It’s great to share ideas with like-minded people. It’s also interesting to see opposing viewpoints and have the ins and outs of these positions explained thoroughly. My question is simply has anyone ever actually been moved to change their mind about a heartfelt issue, not something rather insignificant like whether peeps are better micro waved or just like that out of the box, but something important to them, a central belief of some kind, because of a post or even several posts they read articulating an opposing point of view?
