The flag I carry as my avi was flown by the fiercest and most brutal empire the world has ever known, yet you can buy a t-shirt with the Union flag emblazoned across it and walk down Fifth Avenue with legal and moral impunity. The Third Reich was a ***** cat compared to the British Empire, yet the Swastika is more stigmatised than the Union flag. I can only wonder as to why that is (well, I've got a fairly good idea).
I admire your honesty.
You can't hide from documented facts, but you can sure ignore them, which seems to be the case with the Union flag.
The British empire eagerly committed genocide on three continents, wiped-out and enslaved millions and regarded natives as little more than animals. Overall, it probably killed more people than the Roman Empire and the Third Reich combined. And don't forget that we were the ones who invented the concentration camp, the most infamous of all things 'evil'.
The difference being, is that what the Union flag stands for doesn't really pose much of a threat to the world's power brokers and the international establishment. The Swastika in its Nazi form, however, does. A racially-aware/conscious White race would pose a huge threat to the New World Order, which is why any signs of developing racial solidarity are stigmatised.
