I use people's preferred pronouns, when I do, because I have been asked to don't have a reason not to. When at work, I rarely accidentally 'misgendering/use sex based pronouns' with service users, but I do tend to slip a bit otherwise. This is because/when I am not attending to my words in the same way as I do with clients.
Slip ups haven't, to date, been met with hostility or aggression. The minority haven't said anything, and I tend to let it pass, and switch back, rather than correct myself in the moment.
My general manner/style is one that puts people at ease. Unintentional misgendering is evidence that I too am at ease. If my slip up is noted or corrected this doesn't stress me out. I think this may be a contributory factor in me not finding it difficult to meet the request in the first place. If it made me anxious I think I would be reluctant to try.
In general, gender non conformity and people having trans identities doesn't make me feel ill at ease - which is why I slip up if I stop paying conscious attention. I don't feel at ease around people who are agitated or dysregulated, and I tend to go in to 'work mode' on these occasions, and become more vigilant about my behaviour, including the words I choose- not just pronouns.
I typically encounter people with trans identities a couple of days a week at work and, maybe, once or twice in work-adjacent contexts. In my private life, a couple of my wider circle have relatives who have trans identities and very poor quality of life. It is very rare for me to see these relatives, but the friends talk to me a lot about them.
I rarely encounter trans activists IRL
