"Vaccination causes autism" "My son turned gay from vaccinations!" You probably see lines like these across facebook and other social media, and hopefully all of you are aware that they are nonsense. Any person with basic knowledge of biology know how ridiculous these claims are, but nonetheless there is a huge movement behind it! Most of all it enrages me that it is allowed for people to not-vaccinate their children with these arguments and risk the health of many around them with their idiocy! "It's the parent's / child's right to choose!" No, it may be their body, but they lack the knowledge behind their choice and thus are unable to make this decision. All the child sees is a needle and thus pain, so of course they wouldn't pick that. The parent is dumb enough to believe the lies of non-scientific 'researchers' and will decline. Autism is a mental disorder that can be found on the chromosomes 7, 15, 16 or 17. Chromosomes are little pieces of data containing DNA. Your DNA is also called the Genotype, and as any first-grader has been told the Genotype cannot be altered by influences after fertilisation. In short: Vaccinations cannot cause autism. Let alone homosexuality. Don't let me get started on all of the other idiocy I see people spew!
