Well the nothing being given up already happened, or more accurately almost everything was already lost in Bostock, other than the religious exemption. The religious exemption here doesn't seem big enough to me, but personally I think all discrimination laws against private citizens/companies (as opposed to those hitting government) are bad.
The gain is that instead of religious exception being a vague empty space where we don't know how big or small it is, it is now defined in law.
Also, the deep state won't be able to do much with this. The relevant parts you are (rightly) scared of are done by lawsuits, not administrative actions. If anything, this actually limits what the deep state can sue you for. That vague empty space? Currently they can sue you for doing anything in relation to that.
Now my 'everything' part was a slight overstatement, but it could give Republicans all the religious protection they might want.
No, that's not how employer discrimination lawsuits work. They can sue the employer (not you) for allowing a harmful work environment if you are a fellow employee there and you create one and then the employer does nothing about it. Note that they already can sue for this under current law. On top of that, the bill says it must be a sincere belief.
And the wrong pronoun thing is easily avoided by referring to them by name.
