My cockatiels have learned that “Hey Google, broadcast it’s dinner time” means it’s time to fly to the table and ambush the food as it’s delivered.

I don’t think those people would use the term “regressive,” because that term has inherent negative connotations. Their goal isn’t so much to “regress” as it is to “conserve” - maintain the values and power structures of the past. What a progressive would call progress, they would see as a decline. What they’re losing by ceding LGBTQ+ rights is more subtle than losing their own rights - they’re losing (or think they’re losing) status, privilege, moral authority. Their position in the social hierarchy drops if there are fewer people to look down on.
