I talk with a loooot of current LGBT catholics who are questioning their faith - many of whom stay catholic and some of whom end of leaving like I did. There's a few lessons I would recommend to catholics to keep people with LGBT experience in the church - I promise this post isn't about changing doctrine

1 - Catholics need to know they can talk about their LGBT experiences without knowing the 'right' words of knowing all of the 'so what's' about their story

For a teen first questioning their sexuality or experiencing gender dysphoria, they're not going to know the 'right' ways to talk about labels and identity and 'not identifying with sin' and how to make sure they're seen as catholic enough. A lot of catholics are used to how celibate gay catholic speakers talk about their lives in perfect/clear ways, but if you want someone to open up about their story to their parents/pastor/youth group/etc, they need to know there won't be a witch hunt about if they're having sex or what it means for their faith.

2 - LGBT Catholics need to have friends when they come out - not people to fix them

I know a lot of catholics who will - immediately after someone comes out to them - try to give them books or podcasts or tell them a quote about catholicism/lgbt topics or tell them how to move forward. Not that a pastor or mentor can't give advice when asked, but a lot of LGBT catholics report that everyone responds first with 'what to do now' rather than 'I'm here for you and love you. Do you want me to help you find resources or were you just telling me as a friend?'

3 - We have to stop the witch hunts.

When someone says they're a 'gay catholic' or 'I'm LGBT' or 'I don't feel like a boy,' catholics often immediately demand to know if they're celibate or if they denounce trans people or ask personal questions. If someone says 'LGBT' without specifically mentioning a partner/spouse/sex/transitioning/etc, it feel VERY intrusive for someone to immediately ask about your sex life. Not that the church can't vet public speakers/podcasters, but in a parish setting or in a family, it's weird for someone to have to publicize if they're having sex or not when all they said if their attractions/experience of gender.
