Rarely, but it happens on occasion. Not often from exchanging views with other people, but rather from a combination of observation and the passage of time. It took me a good many years to more or less cement my views of religion, humor and humanity while my views on contemporary politics constantly change (supporting an idea, but knowing that individual most likely won't do as promised or recognizing that the idea has become skewed).
When I speak to others on matters of opinions and ways of thinking, I don't view myself or my "opponent" as right or wrong. Just different conclusions reached from different circumstances and perspectives. Others may view it differently, like some pseudo-competition. I try damn hard to understand where each person is coming from and to learn from them if possible, but some seem to have an erection for eristic exchanges where the end result leads to nothing and the arguments more or less full of the "my way of thinking is right, you're way of thinking is wrong" sentiment.
In cases where actual evidence (numbers, quotations) can be used, then yes. Right/wrong exists and opinions can easily be changed. Otherwise, you're likely just going to be shooting at a strawman or Aunt Sally. I often fear that little yellow mail symbol because it seems an inevitability and I despise repeating myself.
