There's something that you've got to understand here. A LOT of Republicans are uncultured southerners. Many Democrats believe that since a large portion of republicans are uncultured southerners (including the current president), the country will go to hell in a hand basket based on the poor decisions that will be made in the future. For the sake of not having another civil war and further killing the country, many of the Democrats suggest leaving the country. Now, this may seem a bit extreme, but many Jewish people wanted to get as far away from Germany while the Hitler was at the helm, so maybe it's not so impractical afterall. Now, I'm not calling Republicans Nazis, nor am I referring to George W. Bush as Hitler. I'm simply stating possible reasons and examples.
Who made you God to say "I'll take your life from you"?
