People like dangerous bacon and notyetdead are not here to share an "opinion". They have a job and they are paid for it. It doesn't really matter what you say or think, they are here to promote an agenda while making it look like it's just someone from the crowd sharing their "honest to god" opinions.
So, don't waste your time even reading them as they are not writing their opinions; they are not allowed to think or agree with anyone who opposes vaccination. They are a part of what is known as "grey PR". Paid to quote someone else's lies. It's a job that pays well as it has a bigger effect for a lot less money then advertising or political payoffs.
