Is the confederate flag considered offensive by the majority of America?

I think to some people it is, but it shouldn't be.
The Civil war was fought about States rights. They didn't want an over reaching Federal Goverment telling them how to live. I think most people can agree with that, not wanting to be told how to live.
Slavery. I'm sick of hearing how the Civil War (Which was really a War of Secession) was fought about Slaves. First What is Slavery? It is the ownership of Labor, if you are carrying debt to credit cards, cars, school loans, etc you are a slave to the people who you owe the debt to. They own your labor because if you stop paying, they take back the item that you bought that put you in debt. Thats modern Day Slavery, something most Americans accept willingly. The other type of Slavery is EXPENSIVE, and very few Southerners could afford it.
Here's another Fact, Slavery in that form would of died withen 15-20 years, so not something anyone would fight a war over.
No one Today will agree that Slave Ownership is ethical or moral. Here is another Fact, the people alive today claiming Racism keeps them down, and that it goes back to slavery etc. The War of Secession happened almost 150 years ago, very few people if any thats alive today, knew anyone who was a slave.

I think that the Confederate flag has some historical relevance and with that it ties into slavery in the United States.
I think most of us are mature enough to know that the flag is not a rallying point for all racists to cling to.
Yes there are bad people who use the Confederate flag to further their causes, but I am guessing here, many people just grew up with it and its a symbol of the South.
Any flag can be associated with hateful things, the Nazi flag for example. If you want to identify flags with horrible acts and let that stick there are hundreds of other countries flags that can be easily identified with slavery and racial inequality. South Africa, Saudi Arabia, Pakistan, Ghana, Somalia, Rhodesia, and many other countries where today slavery still exists and people are treated differently just because of how they look.

This is a question that can best be answer by a person that has experienced racism by those that fly the Confederate flag. Try doing this apply make up that darkens your skin and wear a wig that gives the impression that you are a person of color, then go into an establishment that displaces the Confederate flag.

SGT Earl is correct in most of his response. The "States right" that was being debated was the right to regard people as property. Slave states only rebelled when the political party that was heavily abolitionist was voted into the majority. They understood that no further slave holding politicians would be added to the Senate with our western expansion. They were paranoid that it would lead to eventual abolition. Being a Southerner I heard all of these things growing up and believed them. "Slavery wasn't that bad," "the war was only about States Rights," and that "the South only lost because they were outspent by the North, that the South had better soldiers and officers." All of these are false. If you would like to see exactly what Southern politicians were discussing in their own words and see what the war was fought over, read "Confederate Emancipation" by Bruce Levine. Hearing Jefferson Davis resist emancipation in order to save the Confederacy is an eye opener.

Heritage? Racism? There's German in my blood, but you won't see me fly a flag with a swastika or any other flag that is associated with my other heritages. I pledged allegiance to the flag of the United States of America, and to fly any other flag is treasonous.

Depends on how it is used

Heritage

I will pose a question to answer this question. How do the people persecuted under Nazi Germany feel about the swastika?

To me it's a banner of treason. If it happened today, it'd be viewed as a domestic terrorist plot to take down the United States government and that's what it was.

I fly it everyday. I'm in the marine corps. An I am from a small town in GA. That flag represents so much to us southerners. I treat that flag just as carefully and as respectfully as the American flag. Not racist. If people think it's racist the are a little dull.
