You may not like Joe Biden but he is our president. I may not have liked Donald Trump as president, but I didn't fly a flag or display a bumper sticker using vulgar language in front of children and adults to register my dislike. The office of the President of the United States must be respected, no matter who holds that title.
Some people seem to be digging deeper into disrespectful, hateful and vulgar rhetoric. They're digging themselves into a hole. I think Jesus called this hell.
If nothing else, please take your flags and bumper stickers down. Display them in your own home, not for all the schoolchildren to see.
