I personally think there are holidays that can go. I personally hate Thanksgiving, and it has nothing to do with my birthday sometimes falling on the last Thursday in November.
Columbus day is also stupid. I get why it exists, and making the day a national holiday did do some good. But we're done with that now, it's fine to let it go.
St. Patrick's Day in the US is dumb. Same with Cinco De Mayo. Those aren't even our holidays, just an excuse to drink.
You know what is MUCH more interesting that Halloween? Día de los Muertos is a much cooler holiday around remembering the loved ones you've lost. My town has a festival every year, and it's pretty cool. Plus, all the spooky stuff is still around, but in a different way.
I'm going to start celebrating Christmas the way the Germans do. Krampus is awesome too.
