Diseases are not a personal choice. Vaccination is not something you choose, like clothing or music. It's a basic requirement for a healthy society.
People that don't get vaccinated are basically saying "Well fuck society, most of YOU are vaccinated so I'm just going to cheap it for free and hope that so many of you don't get diseases that I won't meet anyone sick." Um yeah. That's the same logic that has people running Windows boxes with no antivirus programs... those same bot-net infected zombie boxes that are sending out all the V|AGRA C|AL|S R0LEX P0RN emails.
But I heard if you don't want to vaccinate your children, you can get a TOTALLY WORK SAFE NIGERIAN BANK ACCOUNT for free!
