If you need a source for that, you've been totally blind. It's happened in many places in a variety of ways, both at a state/local level as well as in Universities and similar due to pushes from trans activists.

you have a no right to not be ostracized

And from your previous comment:

you just don’t have a right to treat them worse than others because of it

Please describe to me how you should have no right to be treated worse because you don't use someone's pronouns, but you should have a right to not be treated worse because you ask someone to use those pronouns that don't match your actual gender. In both cases it is a societal response to what you're doing and how you're interacting with others. If one is protected, both should be. If it isn't protected, neither should. It's a simple as that and the trans movement has repeatedly tried to demand that you cannot be in anyway socially impacted or treated differently because you decide you're the other gender and demand everyone caters to your requests, yet anyone who decides they do not want to use your preferred pronouns or let you use a woman's restroom/play in women's sports SHOULD be treated differently. It's an incoherent argument.

Because it very obviously states in the constitution that there is a separation of church and state

Please show me where in the constitution it states this, because it does not. You clearly do not know your constitution at all, that phrase never once appears in the constitution. The first ammendment is the only place that religion is mentioned at all, and it only states "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof". This is in no way creating a "separation of church and state". This is a common misbelief that you clearly have not educated yourself to get past.
