Giving your opinion if it's different than someone else's

Ok so I gave my opinion on something because this girl asked for our opinions and I gave mine and gave facts to back up my opinion anyways she went on to call me a racist and all these things and a slut. Which I'm still trying to figure out is how the slut fit into what I posted. 
The question was about the republican presidential debate and who we thought did the best. And I gave my opinion. And they replied telling me I was a conservative nutcase and I agreed say yes I am a conservative then she got all kinds of crazy. 
So here's my question. 
1)Out of the first 2 republican debates who do you think did the best?
2) Is it bad to add "fuel to the fire" and keep aggravating the person who asks for my opinion and when given she doesn't like it? It's really funny to see how she'll contridict herself
3) what do you think America needs to return to greatness?
