Instagram users were divided over Trump Jr’s image.

“I’ll take that bet all day long.” —Donald Trump Jr.

LGBT+ rights supporters have responded with anger, with some accusing the son of the US president of transphobia.

One person said: “I worry about the safety of our youth with someone rallying like this and encouraging people to laugh and make fun of the lgbt community. It’s awful.”

Another said: “The bullying needs to stop. It’s not so funny when someone decides to commit suicide :(.”

A third person wrote: “That’s not nice at all and so judgmental..the hate and nasty comments on this post are just awful and so uncalled for.”

A number of news outlets, including Inquisitr, meanwhile, described the meme as “transphobic.”

Trump supporters rally behind president’s son

A number of pro-Trump supporters praised Trump Jr for uploading the photo.

“Freak Show,” one commented. “Allowed out in public. Actions speak louder than words.”

Another suggested that the person in the image could be openly gay CNN news anchor Don Lemon’s partner, writing: “Looks like Don Lemmons lover.”

And a third person wrote: “Well, I’m proud to say he is my President. I have always admired Donald Trump.

“Would love to meet the man.”

Trump Jr.’s father recently won his first court backing on his proposed policy to ban trans people from serving in the military.

The US court of appeals for the District of Columbia circuit overruled a previous decision by a Washington DC federal judge, which had blocked the policy.

It is the Trump administration’s first legal victory on the proposed ban, reports the Guardian.

However, the decision will have little impact because other federal courts have ruled against the policy, with these injunctions applying nationwide.

The US Supreme Court is set to rule on the issue in January.
