There shouldnt be a default to trans.
Because it's irrelevant. It's sex that matters when dealing which this stuff.
If you really want to deal with that, it would be better to ask about your sodding religion, cos that's what this is.
The rest of the world shouldnt be compelled to answer 'what is your gender' when they find it offensive and akin to a religion. We shouldn't all be forced into having a gender.
I do not have a gender. I do not want to answer questions about gender.
It's sexist and it's homophobic.
Find another way without forcing me to have to deal with this time wasting, money pit of gibberish.
I want services to be accessible without having to jump through the hoops of someone else's fantasy.
Ask how someone would like to be addressed and have done with it. It's enough. If they lie or conflate sex with gender then really, honestly, let them get on with it.
It feels like the rest of the world is being held hostage to this - we can't access healthcare if we don't sign up to this nonsense. That's where we've got to and that's really not ok.
