Miles if you can not see why a swastika might upset people then you are not really engaging in a debate. You are just digging your heels in and refusing to see reason. You can entrench yourself there for as long as you like but your argument holds little merit until you can verify such a dumb statement. That does not mean people should be banned from flying a swastika, but you can not expect to be taken seriously when you continue to insist that there is no reason for flying that flag to upset people. The freedom to offend is a right that I am seriously invested in defending, but that does not remove the right for people to be offended.
