Happy Pride Month! 🏳️🌈🏳️⚧️ I want to notice a problem that I (and probably many other people) face and is kind of related to it. However, it applies to some straight people too.
Do not shame people for not being in a relationship. It doesn't equal immaturity. And even if it is related to not being fully mature in some cases, it's fine. Let them wait. I am sick of hearing "You're [age] years old, you should grow up and start being interested in romance". Sorry, it doesn't work like this. Maybe the person is asexual/aromantic. Maybe they're not, but they think they're too young for relationships. It's always valid and definitely not random family member's business to complain about.
Do not shame people for not following your expectations of a binary gender. Not every cis person's personality matches the average stereotype, some are almost the opposite. Some people feel comfortable having a different hairstyle than it is expected of their gender or wear different clothes. And some people aren't cisgender and they are even more tired of people telling them to behave like a [gender] that they don't identify as.
Tldr: be kind to others and allow them to not fulfill your traditional expectations of gender and love life
