You'll have to clue me in on how any oppression suffered by Irish immigrants compared to that of being forced to come here chained together in the bottom of ship holds, then upon arrival, the ones who survived the trip without dying from sickness, exposure and disease, being auctioned off as property to work in forced servitude.
Nobody can foresee the future. I doubt that any human society will ever be perfect, but that doesn't mean we shouldn't do what we realistically can. If reserving one month of the year to acknowledge the accomplishments and achievements of blacks who've stood out and overcome their circumstances helps alleviate a little of the negativity and possibly inspires some younger black people to strive for self improvement, I can't see anything wrong with it.
You certainly sound like you're trying to paint yourself as an injured victim.
I have no idea what your ethnicity is.
Don't care, either.
