Churches will be forced to perform same sex marriages
They can refuse to baptize someone with a name they don't think suitable, so I don't see how gay marriages will force them to change.

If they attend a demonstration of the American Nazi Party, does that mean they're all Nazis? If they attend a demonstration of the Revolutionary Socialist League, does that mean they're all Trotskyists? Or are they doing what they're paid to do?
Employees will be forced to attend sensitivity training or lose their job.
If that's what their employer wants them to do, then they had better do it. If it was a matter of a 10% pay cut, you'd be screaming about the rights of the employer.
