A right-wing pundit has called gay Democratic presidential hopeful Pete Buttigieg a “sodomite” and the “king of cocks” in a blog post.

Andrew Bieszad, who writes for the far-right website Shoebat.com, claimed Buttigieg is too “effeminate” to be elected in 2020.

“A sodomite whose name means ‘the king of cocks’ is running to be president of the US,” he wrote.

“How fitting, and it is without a doubt a subtle mockery of the current state of the US, a nation whose people have embraced sodomy by the super majority and as such, means the nation is on the road to perdition.”

He continued: “Buttigieg gives the impression of a Mitt Romney – one looks at him, and one does not exactly feel ‘attracted’ (in the sense of supporting him) to him, or that he would be ‘strong’ enough to ‘lead America’.”

Bieszad also claimed Buttigieg’s campaign would somehow lead to Senator Kyrsten Sinema, who he calls a “woman of sin”, being elected in 2024.

Buttigieg, the 37-year-old mayor of South Bend, Indiana, officially launched his run for the White House on Sunday at a rally.

He said he was running to tell “a different story than ‘Make America Great Again’.

In his speech to the Pete for America rally, Buttigieg said: “My name is Pete Buttigieg. They call me Mayor Pete. I am a proud son of South Bend, Indiana, and I am running for President of the United States.”

He added: “We live in a moment that compels us each to act. The forces changing our country today are tectonic.

“Forces that help to explain what made this current presidency even possible. This time it’s not just about winning an election, it’s about winning an era.”

The mayor set out a liberal agenda, calling out “violent white nationalism rearing its ugly head” and setting out plans for economic reforms to boost smaller post-industrial cities.

The candidate also paid an emotional tribute to his husband Chasten, to loud cheers from the crowd, “for giving me the strength to do this, and the grounding to be myself as we go.”

Referencing LGBT+ rights, he said: “Take it from Chasten and me, you’re not free if a county clerk gets to tell you who you ought to marry because their idea of their political beliefs.”

He added: “Our marriage exists by the grace of a single vote on the US Supreme Court. Nine women and men sat down in a room and took a vote, and brought me the most important freedom in my life.”
