I'm not sure how speed limits actually make people slow down? Certainly isn't the case when I'm on the road. Not to mention most of the dangerous driving I've seen has been below 25mph, walmart parking lot anybody? Drinking and driving also isn't solved by laws against it. Texting laws just make people look at their phones in their laps instead of putting it up at steering wheel level and viewing the messages. Shoplifting is solved through ink dyes, locked cases, and private security guards more so then laws against shop lifting. How does legal gun ownership vs illegal gun ownership make a difference in who is going to commit violence? If guns were suddenly all made illegal tomarrow I certaintly wouldn't then suddenly find myself holding up a bank. How is drug use the cause of violence? Even if it is shouldn't we charge them with the violent act they committed not the nonviolent one of smoking some plant? The world really isn't all that dangerous for your average person who avoids putting themselves into bad situations, neighborhoods, etc.
Oh and how does any of this connect to the OP's personal preference of not going to church? I'm kinda confused, please explain.
