Fashion designers Domenico Dolce and Stefano Gabbana of Dolce & Gabbana got themselves in deep water with Sir Elton John over comments made about nontraditional families.

“The only family is the traditional one,” they said in an interview with Panorama magazine. “No chemical offsprings and rented uterus: life has a natural flow; there are things that should not be changed.”

Fusion explains the comments further:

It’s a bit perplexing. Dolce and Gabbana are gay, former lovers but they’re against gay marriage and against same sex parents raising kids.

Procreation “must be an act of love,” Dolce told Panorama, according to a translation by the site The New Civil Rights Movement. “I call children of chemistry, synthetic children. Uteri [for] rent, semen chosen from a catalog.” (With this logic they’re also against straight couples going to fertility clinics too.)

“The family is not a fad,” Gabbana went on to say. “In it there is a supernatural sense of belonging.”

Elton John took particular umbrage with the comments, calling for a boycott of the brand.

“How dare you refer to my beautiful children as “synthetic”. And shame on you for wagging your judgemental little fingers at IVF – a miracle that has allowed legions of loving people, both straight and gay, to fulfil their dream of having children. Your archaic thinking is out of step with the times, just like your fashions. I shall never wear Dolce and Gabbana ever again. #BoycottDolceGabbana,” John wrote on Instagram.

John and his husband David Furnish have two sons, born from a surrogate.

Other celebrities seem to be on his side. Many took to Twitter to voice their support of Elton John’s statement.
