So the question is whether you walk away with a chip on your shoulder and a sneer on your lips and make it that much harder for your Latino immigrant brethren to get along in Swedish society or whether you graciously smile and act like a human being towards the lady.

You know what, we all know you're an individual. Unfortunately, you are an individual of a group of people who look similar to you and dissimilar to the rest of the population. That means you will be prejudged by people based on their stereotypes of that group. Sucks, but it's true.

Do you perpetuate the belief that Latinos are hotheaded, unkempt womanizers? Or do you chip away at that stereotype by acting like a human being even to those who mistreat you?

Sounds, from your post, that you'd rather have your long hair, act like a boor, and make the excuse that your people have been kept down in the past so it's time you got your due. If only it worked that way, esse.

"law trumps contract and overrules the EULA"

Err, not necessarily. In most legal systems you can renounce a series of rights granted you by law thanks to a contract. That is definetely the case for liabillity rules. However, the extent to which you can waive your right to sue for liability varies from legal system to legal system and depending on the liability's subject matter. In Europe, most producter's liability for defective products can't be waived. I'm not sure how things go in the US regarding that matter.
