RFK Jr has been pushing anti-vaccine bullshit for decades. He was already taking defensive stances on his activism (Oh, I'm not anti-vaccine, I'm just providing nonsense arguments and clout for anti-vaccine stances) back in 2015.
Kennedy was already pushing bullshit during the UK Measles vaccine fraud/scare, back in 2005. He was doing this along with a few other celebrities.
In fact, he is blamed for spreading vaccination hesitancy in Samoa and the deaths of multiple children there as the result even before COVID: https://www.pbs.org/newshour/health/newly-obtained-emails-un...
I've responded to a few people on this but the comment I was responding to was literally about the last 6 years! The context of this entire thread is about MAGA / Trump! I agree that RFK is hurting and has been for a long time, but that is not what this argument is about!
