Firms from Ikea to a Michelin star restaurant have signed up for a campaign in defense of same-sex parenthood in Hungary, bringing unexpected resistance to Prime Minister Viktor Orban¡¯s anti-LGBTQ crackdown.

The Family Is Family campaign has enlisted 140 companies so far, up from 40 in February, in response to steps by Orban to effectively ban adoption for same-sex partners and enshrine in the constitution the idea that marriage is possible only between a man and a woman. The ranks include international giants such as Levi Strauss & Co. and WarnerMedia¡¯s HBO, as well as small- to mid-sized local businesses.

The drive¡¯s popularity is surprising even its organizers in a country where companies have long been wary of taking a stand against Orban. Hungary¡¯s premier since 2010, Orban has sought to consolidate his hold over courts and civil society, and is embroiled in clashes with European Union leaders alarmed by his authoritarian turn.
