The letter, which was handwritten on graph paper, is addressed to "Christine" from "Dad" and discusses the apparent recent coming out of his grandson Chad. A spokesman for the t-shirt company says Chad is 16 and attends high school in Michigan, and that the company confirmed the letter was real.
The letter reads:
"I'm disappointed in you as a daughter. You're correct that we have a 'shame in the family', but mistaken about what it is.
"Kicking Chad out of your home simply because he told you he was gay is the real 'abomination' here. A parent disowning her child is what goes 'against nature'. The only intelligent thing I heard you saying in all this was that 'you didn't raise your son to be gay'. Of course you didn't. He was born this way and didn't choose it any more than he being left-handed.
"You however, have made a choice of being hurtful, narrow-minded and backward. So, while we are in the business of disowning our children, I think I'll take this moment to say goodbye to you.
"I now have a fabulous (as the gays put it) grandson to raise, and I don't have time for a heart-less B-word of a daughter. I [sic] you find your heart, give us a call. ? Dad."
The anti-hate group that posted the now-viral letter says it sent Chad a t-shirt that reads "Some Dudes Marry Dudes, Get Over It," and sent the grandfather a "Straight Against Hate" hoodie.
On its website, the company calls itself a private t-shirt company with a charitable mission to fight homophobia.
"We believe the world would be a better place if good causes had the same savvy marketing as products like iPods, soft drinks and designer jeans," its FAQ says.
