Nasty variations are a red herring, the changes are so small that any medication or vaccine that works on one variant will work on any other. Anything else is contrary to current knowledge or plain lies.
Anyone who is fit enough to be out and about will not be infectious despite what the authorities say. To pass on the virus you will need to be carrying a serious level of infection, as with influenza, this will make you feel pretty damn poorly, you will be tucked up in bed, struggling to make it to the toilet, let alone the pub.
The lockdown, face masks and other restrictions are simply a way to coerce you into a taking a vaccine, developing a digital ID and exercising total control over you. That is a best case scenario, worst case is, well, you work it out.
