On a similar note, if you're going to tell someone they're wrong about something, you owe it to them to explain why. Otherwise they won't (nor should they) take your feedback seriously.

I did. I said the person was building a straw-man and can solve it by understanding the topic more. That means research free market capitalism then present an argument.

IMO if you're going to tell someone they're attacking a strawman, you should point out specifically what they've got wrong about their opponent's argument. Otherwise any random person in the world can simply say, "Strawman, read more plz".
