Totally fair, and I think that’s why allyship and solidarity are so important. I can’t speak to what it feels like to have a chronic disability, but I can amplify the voices of those who do and help to organize broader coalitions in support of accessibility.
No chronic illnesses and not LGBTQ here, so please correct me if I get anything wrong.
The reason many LGBTQ issues sees widespread support now wasn’t because governments and companies decided it was ok, it was because of decades of small battles and struggles that really accelerated into widespread acceptance throughout the 10’s, and to which we are already seeing a backlash in terms of the attacks on trans rights (just to note that acceptance is far from complete or just a constant journey in one direction).
Companies adopted pride not because they are allies but because it became more profitable to be pro-LGBTQ than against. Govs don’t work off profitability exactly, but public opinion shifted so far that Obama went from tepidly approving of civil unions to basically every mainstream democrat being pro-LGBTQ now. Even many Republican senators signed on to the Respect for Marriage Act in 2022.
I don’t have a lot of answers for why that doesn’t exist for people with chronic issues / disabilities yet. I’m sure there are many people working to advocate to make it so and I think we all have a responsibility to encourage accessibility as a right. I don’t think anyone saw the acceleration of pro-LGBTQ popular acceptance that was the 10’s coming, and I don’t think you can attribute it to one particular cause. The tough and unsatisfying answer is “it’s complicated,” but I hope that the example of LGBTQ progress can be a source of solidarity and support for advocating for accessibility.
It was first seen in online queer activist circles around 2004. You can read a little about it here. Latino is traditionally masc/neutral but English style guides also said the same about “he” when referring to someone of unknown or unspecified gender for a long time, which has largely fallen out of use for singular “they” now.
Personally, I don’t use Latinx in writing to refer to all Latinos/Latinas as polling has shown only 2-3% of people readily identify with it. But I do think you absolutely should use it if that’s how someone personally identifies.
