Who cares when orangemen or orangutans for that matter chose to celebrate ANYTHING?

I am reminding YOU of the actual date of the battle. Another (Aughrim) took place on July 12 and was considered THE significant "off with the Catholics" battle for more than half a century, and commemorated as such...But Catholics fought in that one with Great Courage, dying in their thousands for their cause...Pesky stuff! At the first opportunity, commemorations of that battle were changed to celebrations of the Boyne one, or both. An occasion to enjoy a jolly good day of free expressions of bigotry. Catholics fought "less well" in Boyne, one hears, and some actually believe. Scorn could now be added.

And what gave Protestants their chance? The adoption in 1752 of the Gregorian calendar which switched the Boyne date to the 12. Personally, I'm shocked at the adoption without a quibble of something so patently popish by rabid Protestants, even if it gave them the opportunity to downplay Catholic heroism. And this is why I EXPECT that you, at least, will stick to your anti-Catholicism in all ways and all things, and use the Julian calendar exclusively for all "Britannic" pre-1752 dates. It's a question of integrity really.

Unless, of course, you also have something against Caesar. In that case, there's always the Mayan calendar, the Islamic calendar etc.
