LGBTQ bars in Milwaukee, Wisconsin, are banning customers from wearing Jeffrey Dahmer Halloween costumes because the famed serial killer notoriously preyed on the city's gay community.

The convicted serial killer targeted the gay male community in the Wisconsin city during the late seventies to early nineties. Dahmer killed 17 men and boys, whose bodies he dismembered and occasionally ate.  

Jeffrey Lionel Dahmer

Jeffrey Lionel Dahmer (May 21, 1960 Ð November 28, 1994) was an American serial killer, who murdered 17 men between 1978 and 1991 (with the majority of the murders occurring between 1989 and 1991). His murders were particularly gruesome, involving rape, necrophilia and cannibalism. With evidence overwhelmingly against him, Dahmer pleaded not guilty by reason of insanity. The court found Dahmer sane and guilty on 15 counts of murder and sentenced him to 15 life terms, totalling 957 years in prison.  (PA/PA Images via Getty Images)

Two gay bars in Milwaukee, D.I.X and This Is It, wrote on social media prior to Halloween weekend to warn patrons that Dahmer costumes were banned.

"We are here to have a great time respect everyone and make sure everyone feels welcome and comfortable," D.I.X. wrote in a Facebook post. "No Jeffrey Dahmer costumes at the bar please."

"Well said," one patron commented on the post.

"Mad respect for not allowing Dahmer costume" another wrote.

Another bar downtown is also warning its customers not to show up in a Dahmer costume.

This Is It also posted a Dahmer costume ban on Facebook, saying it has been getting phone calls ever since the Netflix series about the serial killer aired.

"In solidarity, with other Queer establishments, this Halloween weekend, we reserve the right to refuse access to anyone wearing hateful, racist, and otherwise disrespectful costume choices." This Is It wrote in a post on Facebook. "This includes anyone dressed as Dahmer."

Online retailer eBay banned any Halloween costumes evoking the serial killer from being sold on its platform.

"These items are banned on eBay and are being removed under our ‘Violence and Violent Criminal Policy,’" an eBay spokesperson told Fox News Digital in an emailed statement. 

Many on social media have been vocal about how dressing up as the real-life criminal is wrong, pointing out the insensitivity toward victims’ families.
