Fireworks & celebrating the magnificent founding of our country is non partisan.
To us and to other normal people, sure, but don't forget these are the DUmmies we're talking about.
1) EVERYTHING is about partisan politics to them.
2) They hate everything about America. They put on a patriotic front when one of their own is in office (Usually so they can then use it to openly accuse those they disagree with of treason), but it barely conceals the deep hatred they have for our country and its people.
Last night, I was able to see about three different fireworks shows from a hilltop church next to my apartment complex (A hurricane years and years ago apparently took out a bunch of trees, so there's a great view all around). There was a nice big group up there watching it too, people of all ages, races, and probably political views enjoying this key aspect of celebrating our country's founding. I found that quite inspiring to see.
Cause there ain't no doubt I love this land, God bless the USA.
