There's already legal precedence for this.
Churches that preach racism do not get a tax exemption. For instance, Richard Hale's "World Church of the Creator" does not get a tax exemption for their views that God opposes race mixing.
So once you've established that sexual orientation is indeed a protected status under the law, churches that discriminate should lose their tax exemption
You know what, I can agree with that, based on logic, if not on ideology. Just realize it means that many of these churches will go down the road I do... if the Government is forcing me to support the poor and such through taxes, then there is no need for me to do any more chatty beyond that. For me it’s an ideological choice. For the churches it will be a financial one.,
