Actually, California law already did away with the meaning sex or gender markings on public restrooms everywhere about five years ago. Under current law, anyone can use the gender of restroom for which they best identify. So this just bill would just change the sign and take the problem to the next level.
We lived in California when the law was changed and fortunately do not now. My wife experienced boys and girls using the toilet together and always challenged the boys for being there.
The very powerful homosexual community in California will push to demolish anything that gets in the way of their agenda to "normalize" their sin into accepted behavior while stopping any attempt to show the sin, for which they identify themselves, to be what the Lord has declared it...sin.
Stand by...it's going to get worse. Please pray for the Christians who live there as well as their safety in the midst of all of what's happening.
