You are wrong. It matters if you do something warranting eviction.<p>The supreme court ruled in Brown v. Board of Eduction of Topeka that racial segregation is a violation of the 14th amendment. This means you cannot evict people even from your privately owned businesses because of their race due to the commerce clause: <a href="http://en.wikipedia.org/wiki/Commerce_Clause" rel="nofollow">http://en.wikipedia.org/wiki/Commerce_Clause</a><p>So if the people with the bumper stickers were black and asked to leave because they were black, it would be a slam dunk case against them.<p>Now we may see if this reaches the supreme court and whether they protect people from being discriminated for their political views.
