They denounce it because they were told to by Fauci.
For those who think that government is benevolent and looking out for our good, or at least that government is a necessary evil and not a deadly malevolent evil run by secret societies:
we already have a cure for cancer (hint: it is another dog de-wormer) but the big drug companies will not allow it in the USA and government helps them keep it out of the country. It can be cheaply bought in other countries and is very effective. I know people here who are taking it and have put into full remission stage 4 cancers of the brain and liver. I checked with my pharmacist and they can make it but it would cost $411 for one pill; while from foreign country it costs $7 for a package of pills.
Do you think one politician would speak up about this? If they did they would be likely murdered or their children murdered.
