Non western cultures do have their own indigenous roles for LGBT people. For example In India trans folk had traditional communities and villages which were repressed by colonization and is now being replaced by a western style pride culture. That replacement IS a part of imperialism. Many examples of this
We saw this clash when Matty Healy kissed a man on stage as a protest of the Islamic Malaysian states repressive policies in Kuala Lumpur. That kind of pride protest is normal in the west to celebrate LGBT culture but in Malaysia it set back DECADES of progress by the Malaysian lgbt community and he was condemned by all parties. The right wing anti western indigenous nationalist parties used that as an example of cultural imperialism done by white people and peoples rights were impacted.
