If you never been in jury duty, both sides look at the selected jurors (sometimes 20-40 ppl) and their goal is to shave it to a smaller number, like 12.
Wear gauges? Have purple hair? Be a person of color?
If you don't fit a specific profile to help them win... You're gone.
During one of the selected cases where I was part of being selected, they absolutely asked you questions about your job and family, to get a sense of your background.
So, technically, the USA has what is called "Protected Classes" such as race, ethnicity, and disability who, for the reason of being who they are, cannot be excluded or disadvantaged as a result of.
In most of the USA, sexual orientation or other identities are not in any way protected.
Except for like a buttload of nuances and small changes and court decisions over the course of a century or two.
The point op is making though is that in court a attorny can strike people with minimal reason. Which includes all those protected classes. They have a limited amount of those strikes but they can do whatever they want with them.
For instance, if the person on trial is part of "religion A" and that religion is known to stick together with a cult like fervor an attorney could strike strike a juror of religion A for "cause".
