I totally agree. I've had some great and epic conversation/debates. There are some people who are reasonable enough to have a conversation with.
I avoid those who just want to call names and act like anyone who disagrees is obviously wrong. There is no purpose in having those discussions. I love a thoughtful disagreement and it is rare that it doesn't change my perspective at least a little.
It is one of the best parts about the platform and it is a shame that so few atualy use the opportunity but instead say crap like:
"its really such nice post. yes true opinion its right have a good day"
At times it's so hard to win on a debate..it gets heated...
