I have done my best to stay informed about $CONTENTIOUS_ISSUE. I read what I can about it, and hope I'm informed enough that my opinions about $CONTENTIOUS_ISSUE are similarly informed.
I've got good friends on both sides of $CONTENTIOUS_ISSUE who are -- for very good reasons! -- not objective about it. I don't think you need to be objective to have a valid opinion, either.
But, if I am not talking about $CONTENTIOUS_ISSUE very much... that's possibly part of why.
