Discriminating against people because of their weight is not limited to famous people in music videos. It's hard on everyday people who have had a lifetime of conditioning to not speak out and endured subtle and not so subtle insults.
This is my call for airlines to make their seats larger, so fat people can travel without experiencing shame, humiliation, or discomfort. Everyone deserves to fly without enduring these hardships and it's time that we start talking about it.
If referring to someone as fat were the same as referring to someone as a brunette or tall or freckled, a woman's refusal to describe herself as such would be weird. But, collectively, we're not there yet. The word "fat" has power because the word "fat" has consequences.
