How long have you known about rizza Islam? This is back from 2019 where he's pushing autism being caused by MMR vaccines
Edit: He's also pushing misinformation about there being harmful metals in the MMR vaccine.
This is shyt you can look up online to disprove that but people like sway and Aries Spears won't be able to call him out on that in real-time.
His overall scam is to push medical skeptism to eventually lead people to his scientology based naturopathic remedies (ie the detox center he and his mom used to run).
