To acknowledge the history of prejudice and history of hate against them? Kinda like those who support keeping Confederate monuments/symbols/flags in place? Here in Alabama (Roll Tide!), Jefferson Davis' birthday is still celebrated as a holiday.
I'm a white man. When white men first got here, the skraelings (What the vikings called the natives) hunted them down. We was oppressed! Do we have a White man's history month? Nope. A United White Folks' College Fund? nope. Viking Awareness Day? missed it...
How about Heterosexual Pride marches? Uh-uh.
If you want to be equal, be equal.
Trying to one-up everyone else just gets tedious. I don't give a darn what you do in the privacy (yes, PRIVACY) of your own home with a consenting adult. None of my business, as long as you aren't breaking any laws.
Why even be bothered to wave a flag and have all that stuff unless you're recruiting? What is the point of being so conspicuous if you want to be 'equal'? No one else is doing that stuff. Which leads me to the conclusion someone has a messed up idea of what equality is.
Equality isn't paybacks, it isn't imposing wrong on people who never wronged you--that only fires up another cycle of resentment and when (not if) the pendulum swings in a different direction it will come back harder than ever. If you want equality, if you want live and let live acceptance, the present course of action just might be contraindicated.
