Elephant vs. Donkey

So tonight I watched my boyfriend and sister have it out on their respective blogs about politics. I have come to the realization that we are all passionate people with our own views. We are not going to change. People with views that differ can try and see the other side of things till the cows come home, but we will still believe down to our core that we are right. I will never understand why Democrats think the way they do about basically anything. I make up my own mind on issues, regardless of party lines. I don't blindly listen to everything an elephant has to say, but majority of the time, I like the peanuts he's spewing.

My boyfriend is concerned because I agree with basically everything my sister says in her blog The Ranting Republican. My sister is finishing up her 2nd year of law school and can verbalize thoughts and can argue better than anyone I know. He is finally seeing just how different we are in our views of the world. Is it something that we should be worried about? Absolutely. Can we find common ground on topics? Not likely. Can two people still love each other despite all of this? I think so. My question is: Can a relationship survive when two people are so completely different?
