I like to take things right back to a starting point - but that is too far for a lot of people.

For example with vaccinations I'm not only say they are dangerous - I'm saying the process doesn't work anyway - even if it was safe, which it isn't.

And with global warming I'm not arguing whether warming is man made - I'm saying that the planet is cooling and we are going back into the default state of being in an ice age like the planet nearly always is.

So it doesn't matter what they do, not even nuclear radiation could outdo the sun
