Some guys in the comments were discussing and complaining about the flag.

So what is the meaning (nowadays) of this old flag, what does it stand for
in everyday life, e.g. when someone has a sticker with it on his car ?

Though I'm not from the States, I have spent some time there, and in the southern states, so I know the confederate flag also quite well.
From Wikipedia:

Opponents of the Confederate flag see it as an overt symbol of racism (especially directed toward African Americans), both for the history of racial slavery in the United States, and the establishment of Jim Crow laws by Southern states following the end of Reconstruction in late 1870s, enforcing racial segregation within state borders for nearly a century until the Civil Rights Movement. Some hate groups use the Southern Cross as one of the symbols associated with their organizations, including racist groups such as the Neo-Nazis and the Ku Klux Klan.[17] The flag is also sometimes used by separatist organizations such as the Aryan Nations. The Aryan Nation also uses the U.S. flag as well as the Christian flag displayed in some Protestant churches.
Supporters of the flag view it as a symbol of heritage and the freedom of the distinct cultural tradition of the South from the oppression of Northern government. Also, in light of some schools and universities banning it as a racist symbol in their "speech codes", it could also be seen as a symbol of freedom of speech.[18]
White southerners often claim that they see the flag as merely a symbol of southern culture without any political or racial connotation. An example of this would be the Bocephus Rebel Flag often sold at concerts performed by country music star Hank Williams, Jr or Kevin Fowler, heavy metal band Pantera, and southern rock band Lynyrd Skynyrd.

I hope this helps...
