The left will not stop with schools, sporting events and other so-called public places. Bathroom rules, multi-gender-based pronouns, so-called offensive speech rules… These will be enforced everywhere.
Your spaghetti supper is a secular event. Evangelism might be, too.
The Washington Post’s Eugene Volokh says, Massachusetts: Churches may be covered by transgender discrimination bans, as to ‘secular events’

This will be illegal.
Now some might think this is fine: Everyone should use the pronouns that the subjects prefer, the argument would go, even if the speaker views such use as endorsement of what the speaker sees as falsehood, or of a wrong-headed ideology. People shouldn’t say derogatory things about transgender people, at least when those people can overhear.
Maybe churches could do something different in sermons, or behind closed doors — but once they open their doors for “secular events,” church leaders have to use the words that the law requires, even when they view them as false or even blasphemous, and have to suppress offensive speech by their congregants. I don’t share this view, but I take it that some do.
But I just think it should be clear that this is where these rules are headed, at least in places like Massachusetts but likely elsewhere as well.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
