I never had issues referring to people by their preferred gender.
How do you think they feel if you refer to them by the gender they were assigned at birth?
I don't know, everyone is different.
Yeah, that makes sense. I mean it's okay to ask people who don't make it obvious, which gender they want to be referred as.
I think I am a good person so I ask for pronouns before talking with them.
That is very kind of you to consider other peoples feelings. Not everyone is willing to do it because it can be confusing and inconvenient sometimes.
