All of North America accounts for less than 1/5 of InBev sales. Budweiser‘s American sales are a fraction of that fraction.Look at any month in the last year and you will see that much variation.
InBev will be just fine. They probably lost less than 1% of sales for a couple months.
The specific marketing executives who used Budweiser to make a culture wars point? Ants riding along on the Borg. Or used to be. They are taking a leave of absence. Will probably be replaced by someone who spends their time thinking about beer.
