Tell me, how do you prevent it?
Laws don’t prevent crime, they define them
You need a police force to enforce it
We already have pervert laws in every state
So the laws already exist
Do we create a Federal Bureau of Potties? Do they have a police force that goes from bathroom to bathroom to make sure the right gender is using the right potty?
Seriously, what is the next step?
These bathroom laws change existing law. They allow perverted grown men to hang out in the same bathroom with your 5 year old daughter and there is nothing you can do about it. Any real man would know that this is wrong, and under current law, I can make sure the pervert pays a physical price for trying to be a pervert around my daughter. You want to make it perfectly legal for the pervert to hang out with my daughter. And you don;t see a problem with that?
Now, thanks to guys like you, if someone physically deals with a pervert being perverted with their daughter, they get thrown in jail because the pervert had the right to be there because he just happened to identify with that gender today.
If alleged conservatives can't tell the difference, and don't think this kind of issue is important, we are doomed as a society and will never manage to find the courage to build a wall and stop Islamic terrorism. We are rapidly on our way to becoming the EU and guys like you are leading the way.
