Not just lgbtq but all marginalised people. Capitalists are incentivised to create and exploit marginalised people under capitalism. They are not incentivised to solve marginalisation because marginalised people have conditions that make them easier to exploit for lower wages and worse conditions.

Whether it's patriarchy which has always held 50% of the population as property of men for free labour and exploitation, or more recently the gender wage gap. Or whether it's racism, where the marginalised suffer worse conditions, maltreatment, poor wages and a tougher time. Or whether it's lgbtq people where their marginalisation has a 22% wage/earnings gap with hetero/cis people. (don't get me started on sex work or being trans and renting or applying for jobs)

Capitalists gain from exploitation of marginalised groups. You will not liberate any marginalised group fully under a system incentivised to exploit others as marginalised people are ripe for exploitation. If you do liberate one group they are incentivised to create another or shift the burden to an existing one.

The liberation of marginalised people can only come with liberation from a system incentivised to create marginalised people. Various pressures we create achieve concessions for marginalised groups but that's all they will ever be, concessions to prevent us overturning the system entirely.
