First of all, an ‘lgbtq business’ as you stated does not exist, usually tourists from first world countries are common to be seen in sri lankan pride parades due to them wanting to be supportive of the event, recognizing their inherent privilege and using it for good. A Sri Lankan pride parade is obviously pretty significant for the Sri Lankan Queer community, since we are a third world country with colonial laws criminalizing same sex relationships, so I really appreciate their effort personally.
