Vandals attacked a window display that featured pro-LGBT T-shirts at the Silver Spring American Apparel store on Monday morning, The Sexist reports, shattering a window in the process. The Georgetown location of American Apparel also received a telephone threat later that day about their similar window display.

The T-shirts in the window bore the logo of the company’s “Legalize Gay” campaign, which is designed to raise awareness about opposition to California’s Proposition 8.

The Silver Spring store has since removed its front window display.

American Apparel has issued a statement in response to the attack and threats. “We don’t find this kind of thing funny and we definitely don’t find it intimidating,” reads the statement in part. The company also offered to send “Legalize Gay” T-shirts to any group in Washington D.C. that is fighting for gay rights.
