There was that thread recently where people were trying to pretend there is no such thing as a stereotypical White Gay, like it's not a known thing in the community, and I felt like I was losing my damn mind.
If you have the monetary or cultural resources to not actually be negatively impacted by day-to-day kinds of oppression, particularly if you are part of a vulnerable minority group, many of those people will find it very appealing to side with the oppressive majority and normalize themselves through their own whiteness or monetary affluence to quickly remove themselves from their own potential oppression so they can be "one of the good ones" while never actually being at risk from the implementation of the kinds of policies that result.
It's not like it's everyone, especially if you know a lot of gay people the percentage will clearly be very low, but the kinds of gay people who are almost eager to fuck over the very group they belong to are usually wealthy white cis gay men eager to cash in as much privilege as they can. Whiteness and financial stability are two of the biggest sources of power in our society, unfortunately, and can easily trump who you sleep with, especially if you're traditionally handsome and present as masculine.
