Let's think for a minute: If I believe that 1) vaccines don't work; 2) that herd immunity is a fallacy; and 3) that acquiring natural immunization with vaccine available diseases are better for me, human kind, and society as a whole than the negative consequences of said vaccines...then it would be socially irresponsible of me to perpetuate this tragic practice. This is a world my children and children's children have to live in. I'm not going to partake in something that is damaging to my society and my planet. My decision is not limited to myself or my child - I believe it is best for the the whole world.
If you don't agree with 1, 2,and 3 above then your view of social responsibility will be different. Why does your view have to be forced onto me? Why do I have to be accused of being socially irresponsible for making a sincerely held and conscientious decision?
I am not getting a "free ride" I lament that others are subjecting their child to this "ride" that is a horrible social/medical experiment that time will show to be a disaster (IMO). It adds insult to injury that I'm doing this selfishly.
But I definitly share your view that it is a tragic practice and one that requires some serious rethinking. For individuals and society.
ETA: I too believe it is a huge experiment with the potential to go horribly horribly wrong. People in positions of power just do not know what they are doing. I don't think they are necessarily evil people, just arrogant. A bit like the people who helped create the financial mess the world is in.
