As CNN’s Jake Tapper noted, the last Sunday in September is set aside to remember the sacrifices of fallen American service members and especially their mothers.
However, NFL players appeared to not have known this and many protested the American flag and American national anthem in pre-game ceremonies this past Sunday, sparking outrage across the nation.
Here’s Jake Tapper’s tweet about Gold Star Mother’s Day:
The last Sunday in September is Gold Star Mothers’ and Family’s Day, when we honor those whose sacrifice and pain is unimaginable. ??

Regardless of their right to free speech and their feelings about the national anthem, NFL players should do more research before protesting on a day set aside for remembering the fallen and their mothers, who sacrificed their sons for the country.
