I think democrats need to grab the high ground on civil liberties, and get on the same page on free speech. This VA school board thing should be an opportunity to support free speech, even when it's speech that liberals disagree with.
And it's not like it's only RW Christians who have contrarian views on LGBTNB rights. There are several religious sects from RWE to Hindu who may disagree with the current prevailing idea. You can't have liberals, if they have any integrity, nodding tolerantly when a Muslim or Hindu questions gender reassignment or self-definition but moving to expel RWEs if they voice the same doubts. Again, the best counter to free speech you disapprove...is more free speech. You can blast that teacher in VA with facts pertinent to gender definition, but you can't fire him. School board meetings are inherently contentious.
