Presidential son Donald Trump Jr. re-ignited his long-festering feud with the LGBTQ community with an abhorrent tweet Saturday about the risks of having sex with HIV-positive people.

This ugly incident drawing anger and universal condemnation among the community sprang from Don Jr.'s tweet responding to a story on the website Queerty. Don Jr. had apparently not read the story and had based his tweet on the story's headline, "What you stand to lose by not having sex with people with HIV."

Don Jr.'s ignorant and flippant tweet to this headline was, “Well I can think of one thing.”

LGBTQ Nation said Don Jr. was implying people having sex with HIV+ people are at risk of dying.

Don Jr.'s tweet revealed his total ignorance about HIV and AIDS, according to a storm of comments on social media sites blasting the president's son for his bigotry and fervid anti-LGBTQ stance. The website explained HIV isn't automatically a death sentence. It said people like Don Jr. have long ignored the facts about HIV/AIDS because it’s easier to make ignorant jokes about it.

“Crucially, HIV is not the same thing as AIDS, which develops when the HIV virus has gone untreated and reaches its final stages," noted The Independent.

"AIDS does often lead to death, but with proper medical treatment the vast majority of HIV positive people reach healthy life expectancies and never contract AIDS.”

David Hudson, the writer of the story, responded to many of the misconceptions around having sex with HIV+ and undetectable people.

“Yes, take responsibility for your health and do what you feel is best for you," wrote Hudson in the Queerty article. "But do so with an awareness of the potential consequences of those decisions. Refusing to entertain the idea of dating an HIV-positive person might just mean you miss out on the love of your life."

The Human Rights Campaign (HRC), the largest LGBTQ advocacy group and political lobbying organization in the United States, on Tuesday urged Don Jr. to apologize "for his vile weekend tweet stigmatizing people living with HIV."

HRC President Alphonso David said the president's son "just proved again what we already knew -- that he, his father and the Trump-Pence administration don’t care about people living with HIV, are undermining competent care and have no understanding of people living with HIV."

He added, "Trump Jr. must apologize."

David went on to say Don Jr.'s absolutely disgusting and ignorant tweet perpetuates the stigma faced by people living with HIV that HRC and LGBTQ advocates have fought so long to end. He also said Trump and Pence must sufficiently fund domestic initiatives aimed at ending the AIDS epidemic they claim to be combatting.

Don Jr. immediately drew harsh, and sometimes horrid, rebuttals to his tweet all over social media.

Actor Javier Munoz, who starred in the Broadway musical "Hamilton," tweeted, “Your comment is 100 percent part of the problem by strengthening stigma which the entire world, the entire world, is rallying to destroy because it is literally possible, within our lifetime, to end HIV/AIDS. This ignorant drivel is all you have to offer? You’re on the wrong side.”

Fellow actor Telly Leung tweeted, “You’re a despicable person. Educate yourself, you deplorable excuse for a human being.”
