obviously you haven't done anything to change their minds, cause if you have its very very easy with all the information out there to change ANYONES mind with the right approach, and don't just walk up to them and be like, YOUR MORONS !!!!, show them how mature you are and ask them if you can sit down with them for a hour to go over a issue that you are dealing with. Having facts right in front of you to prove their old ways and ideas are wrong....

I did this with my parents years ago and its a lot easier than you think... my mother was raised HARDCORE Christian, and my dad is a HARDCORE conservative that listens and agrees to every word bill'o'riley says... so IF i could, its quite possible you can..
