I think the most offensive part of what we refer to as the "confederate flag" is not necessarily the national flag, though it was used as part of it.
[As framing for this next paragraph please imagine a picture of my avatar with an American Flag waving behind it]
It is the battle flag of another nation. If you're wandering around our country flying the battle flag of another country, I consider that an act of war. It should be well within my rights to pull out my musket and shoot on on the spot. But Alas, this is America and we have freedom of speech and such things. That at the end of the day, is what this is about. Here on Team9000 we have many people, from all Ethnicities, countries, and social status. If you want to display the Confederate battle flag, you are more than welcome to. I don't have to like it, I don't have to like you, but I do have to live with it. Because these are the principals I believe in. Freedom of speech is not limited to what I want you to hear. So display your flags.
Now, you have to realize, that this is a double edged sword. If you want us to accept your freedom of speech, you must accept that of others. When it comes down to people making hammer and sickle monuments, or walking around in Stalin skins, you need to be okay with this. Once again, I may not agree with those people who believe that communism is right, however they have every right to state that they do, and show that they do.
Now, you're probably raging about my little soap box about freedom of speech, while noticing that we censor Swastikas, as well as Hitler skins. We do this for two primary reasons:
1.) Does anyone who makes a swastika do it for any other reason than to troll? Honestly, people just make them to annoy others. The way blocks are laid out in minecraft it's an easy shape to make, the building style lends it's self well to it. It's childish, it's trolly, and frankly, it's stupid. But people do it anyway. Those are not the kind of people we want on our server.
2.) Team9000 does have members from Germany.
