There was a time when people could actually have a civil political discussion with those who held different views. For example, at one time conservatives such as William F. Buckley would intelligently debate those who held liberal beliefs. He did not stoop to applying cowardly erroneous labels to them or to trying to discredit their entire existence; he stated his beliefs and he listened to theirs.
Believe it or not, liberals and conservatives are really not all that far apart. They do, as a rule want what is best for their country. They may go about it in different ways and have different beliefs as to how they would wish for their society to be run but the majority of them are not Nazis or people hoping for the disintegration of their country.
Name calling and ridicule really don't have any place in reasonable political discourse unless we are talking about satire. Look at the state the US is in now because so many seem to have forgotten the art of compromise. Compromise does not mean weakness, it means that you are putting your country above your own political beliefs.
It really is time for all of us to take a deep breath and remember that everyone is entitled to their own opinions. I do think the majority of people...not on the Internet...are still participating in civil political discussion and do not fall for all the name calling and personal attacks. It's just that the ones who scream and yell get all the attention.
