I honestly think anti-vaxxers should be prosecuted for their beliefs.
That seems extreme. Why do you think anti-vaxxers should be prosecuted?
They are damaging an entire generation.
People shouldn't be prosecuted for their opinions. How would you feel if you were prosecuted for your opinion?
I have no idea how I would feel. I don't care if they get hurt since they are harming the society.
You are not expected to agree with them but  you should respect that people have their own opinions. You wouldn't want yourself persecuted for thinking the opposite that everybody should have vaccines.
