This is something that does not exist. This is literally fear-mongering. Moving the discussion about autism to something that does not exist, instead of what exists right now, is exactly what I mean when I talk about rampant fear-mongering. How about we focus on trying to make autism more accepted and understood instead of focusing on anti-vaxxers making slippery slope arguments? This hypothetical is literally just another anti-vax talking point to try and get people to agree with them. This is why Autism gets such a bad reputation, it's always about slippery slopes and never about what's happening right now, and if we ever bring it up, people avoid the actual issues around it and go directly to the hypotheticals.
I don't care about the hypotheticals and I messed up by even entertaining the thought of it one day happening. I only talked about it because I wanted to have an open mind and tackle this from all sides, but people are unwilling to focus on anything but the hypotheticals so I'm going to put my foot down too. It doesn't matter and it shouldn't matter, because you cannot detect it in the womb, end of story. Anti-vaxxers only bring it up because they want to talk about eradicating Autism like it's a disease, and if that means getting people on board with a hypothetical that is against Autism, then they'll do it. They know most leftists are pro-choice, that's why they make this slippery slope argument in the first place.
