UPDATE: I received this email from Urban Outfitters.
The charges that we discontinued the t-shirt because of pressure from proponents of Proposition 8 are false. We’re a company that has always embraced diversity. In fact our designers are currently working on a t-shirt in support of same sex marriage. Proceeds from its sales will be donated to a legal fund supporting the civil rights of the gay and lesbian community. If you require additional assistance, please feel free to email us at service@urbanoutfitters.com.Well, I don't know if the pulling of the shirt was related to proposition 8 or not, but I do see it as suspicious. Nonetheless thanks for taking action, it seems they are hearing us out and that good may come out of this fiasco.
Sincerely,

12/13/08: The trendy clothing retailer Urban Outfitters pulled a T-shirt with a pro-marriage equality message within days of the item first appearing in stores and at the company’s web site.
A buyer for Urban Outfitters told shirt deigner Tara Littman of Supprt Shirts that the item had garnered "too much bad press," although New York Magazine said that Littman, looking into the matter for herself, was able to identify only one blog item as expressing a negative opinion about the shirt.

Interesting to note, Good as You has posted an image showing an impartial list of CEO Richard Hayne's campaign contributions.

Next on the queer boycott list? "We report, you decide" ;)
