I don't believe he should be no platformed, but he is a quack and is spreading deliberate misinformation. Not vaccinating your kid should be illegal in any sufficiently advanced society. We have access and resources so no excuse. If you don't want your child vaccinated move to fucking Africa, South America, The Middle East, or South East Asia. See how great life is in a third world country. Then get fucking laughed at by the people fighting for vaccines that you take for granted.
