There is a way to be respectful BY being blunt and to the point, consistently, and answer a real idea with a real idea.
When you dehumanize your opponent, as the GOP has tried to do for four years to the president, it demeans your position and people don't take you as seriously. The american voter is very very weary of all of the BS. meanwhile, The presidents fear of facing his political foes head on has angered his base over and over again, and it's a symptom of the same issue in reverse.
He fails to tell us as individuals how he helped us, and how he could in the future, and Trust me on this one 

, his reasoning is because the last thing the first african american president needs or wants is to be seen as the classic angry black man that conservatives have in their mind when they think of activist african american organisations, like the panthers, farakhan, or malcolm X even. It has been the driving force in his cold mannerisms that even have democratic congressmen screaming for a life raft at times and never getting it. 
Obama is what he is, a calculating lawyer and politician, who plays for the the long game, not the short one.
He is THAT intentionally removed, and at some point we all have to ask ... Does any of this serve our nation and ourselves. Hate and fear reduce american politics to a pinball game, full of flashing lights and noise but if you really try to tilt the game, the show is over.
Right now the game needs to be tilted, because neither of the two presidential candidates feel they have to leave their safety zone to win. 
We have become that divided as a nation, and yes, it most definitely IS due to a concerted GOP obstruction of congress, to damage the first black president that got us there. Romney is now polling ZERO in two polls conducted among african americans. I would imagine they believe that Obama has been unfairly treated, and that they have been vilified because of it. When Romney went to the NAACP convention and basically made fun of them to their face, and then went on later to a GOP fund raising event to brag about it, He jumped the shark with them.
I watch people jump the shark here with every post they make, and that is the issue. Strength of position with no conviction or reason is just plain anger. 
passion and anger are two different things. Ask anyone who has had rough consensual sex because they like it that way, versus someone who was raped. There is a difference, and if you can't tell which is which, you probably ought not play in the field of politics.
I am all for going for the jugular OF AN IDEA, and respecting the person who made the post. Am I successful? not always, and who would want to be all the time.There are times when getting angry is not only not bad, but appropriate. Do you think that Washington was thinking warm fuzzy thoughts about King George OR John Adams?
He was not.
you have to give people their humanity, something so removed on the internet. You also need to show your own.
