This is exactly the same conflict we have on our Australia Day, which others call 'Invasion Day' or 'Survival Day' and mourn about the atrocities of colonialism, and others celebrate by painting their face with the flag, going to the beach, drinking beers all day and having a barbecue.
Did you grow up celebrating it in happy ignorance like I did?
Do you find you are able to cast a different meaning for the day yourself, one rid of its genesis?
(Btw, I just added some links to source articles to the OP.)
Not really ignorance - when I was a kid it was in the school holidays anyway, and it wasn't really about getting people together in the way Thanksgiving was. In a very Aussie was it's more about drinking and barbies, which wasn't what my folks were into. And then as soon as we were old enough to 'get it' there was a lot of awareness of what it 'really' meant. My folks were very conscious of that too.
No, the meaning of the day to me is staled by it's genesis, and I am usually very vocally against it because of this reason. There was a call to change it to May 8th - (m8, maaate - ugh) but I'm not sure they will. There is a big debate about it here everyyear.
