Straight western culture is bourgeois decadence too though. If members of whichever party find flamboyant, effeminate, or stereotypically queer displays of wealth to be better representations of upper class opulance than stereotypically straight excesses like the sports industry or expensive car enthusiasm, that is 100% on them.

This reads like you think LGBTQIA+ people don’t have political movements or presence outside of a western context.

Not really sure what specifically you are characterising as "western" LGBT politics as opposed to "non-western".
