I remember hearing the adage "never argue politics or religion" After visiting ARP for awhile I now see why that's good advice.
I bet not one person has ever read an opposing opinion and said eureka! I seen the light! and changed their opinion.
People tend to see their own beliefs as facts and opposing beliefs as b.s. and no amount of evidence, arguing or power of persuasion actually persuades anyone.
Lastly it seems that when one tires of explaining their reasons for the opinions they hold they just say screw it and attack their opponents intelligence, character, loyalty, patriotism etc. Have fun guys ...sometimes it's good entertainment...but don't really believe you're going to change anybody's mind
