It's not that funny
To make fun of a minority of people that at are at increased risk of discrimination and violence doesn't sit well with me.
If you want to be called some random pronoun just for fun that's fine but please remember the people that just want to get on with their lives and be treated as human beings .
Making fun of a person's gender or sexual identity can be extremely harmful. LGBT people are already at the highest risk of violence, descrimination and suicide. It is not a choice they make or an issue that they have that needs 'fixing', it is attitudes that need to change.
