2020
No one jabbed:
Asympomatic transmission is the main driver of the spread of "coronavirus".
2021
Almost all people at serious risk of bothering the NHS have been jabbed twice, and soon three times:
Jabbed + asymptomatic = no problem even if you have "coronavirus" and whatever protection the jabs may have offered has worn off. Live a free life.
Unjabbed + asymptomatic even if you don't have "coronavirus". Live as a prisoner in your own country, subject to exclusion, discrimination and shame.
The end has justified the means. Injecting people was the end and the means was, and is, fear, repression, deprivation of rights and liberties, destruction of traditional businesses and economy to be replaced with some new way of doing things. Why?
Because.
As you say - Double jabbbed no longer enough - Because that didnt work you now need boosters. Every week. Forever. Because.
