I can see their point, however, historical revisionism is a fickle beast. What's repugnant to some was the pride and glory of others. I'm certain the Sikhs and Punjab fighters who distinguished themselves proudly putting down the mutiny at Lucknow would be pretty miffed to know their legacy has been erased under the guise of "progressivism."
So how long until we in Canada see "Batoche" "Fish Creek" "Cut Knife Hill" and "North West Rebellion 1885" picked out of the colours and guidons of the Canadian Army? Where do we draw the line between what was and what is now? Do the 1812 Battle Honours get stripped because it might offend our American Allies (Hint: it doesn't. It's actually a pretty jocular subject of ribbing amongst friends nowadays)?
Nationalism and crafting a distinctly Canadian identity is a lofty goal. Mainly because it's a fallacy. We beg, borrow, and steal from so many different cultures and traditions that it's near impossible to have something distinctly "ours". Hell the flag of our country was stylized off of the RMC flag, that predated the "colonialist and bigoted" Red Ensign by a good 25 years.
If CRCN is big on the RCN to become "Canada's Navy," that's cool. I hope he renounces the "Senior Service" status and right of line privileges too. RCN can fall in behind the RCCS and before the Infantry. It's more historically accurate.
Much like the Water Corporal debacle from a few years ago, this is solving a problem no one asked to fix. This is not revising or adapting a tradition; this is someone with an agenda using their platform to settle a score.
