The world isn't scary, but it is dangerous. How about you remove the locks from your doors and get rid of any means to defend yourself. I'll bet you won't sleep soundly ever again, and will be robbed and/or killed the second someone realizes that they can get in without a fuss. And I'm not sure about over there but here you can track registered sex offenders. They are f*cking everywhere. I hardly think I'm overreacting. Had I said that I wanted kids and would shelter them from everything by keeping them locked up 24/7 then that would be overreacting. I simply am stating that I choose not to have and kids.
I am suddenly reminded of a radio station personality who believes that everyone should have kids. I don't mean as a suggestion either, he believes that it is everyone's duty to have kids and that those who don't are denying lives to exist. F*ck that guy. Saving that you owe nonexistent people anything is ludicrous.
