Do the rational tech people believe the science of gametes or do they put their faith in a different belief on how gender works?

This argument relies entirely on the (almost always intentional) misunderstanding that sex is the same as gender or its social expression.

They differentiate between biological sex (which is also more complex when considered in full) from gender. It's quite simple really.

There aren't any rational tech people; just tech people who believe they are free of bias.

The rational answers to both these questions is to accept we don't know (whether a fetus has a soul or how many genders) and stop trying to force whatever unproven answer we personally prefer onto everyone else. If you don't believe in abortion, don't get one. If you think there are 2 genders, pick from those. But don't act like you have some concrete proof you're right when you don't...

That falls apart when: 1. You believe abortion is the act of taking someone else's life. 2. You try to dictate other people's speech to acknowledge there are more than 2 genders when the person you are telling doesn't believe it.

Seems weird that you would frame it in a 1 sided way.

Who cares what you believe? Scientific fact/consensus says you're wrong.
