Yes, I understand that it didn't prevent us from catching it or spreading it. It did however, reduce the length of time we were sick. Which meant that since we were her primary carers, that she wasn't without us for as long. Since it DID reduce the length of time and severity of our illness.
As far as all of the other gripes you seem to have around Covid, yes, I agree it wasn't handled perfectly, but since we were dealing with a completely unfamiliar disease, we were working with what information was available at the time.
I don't deny that in hindsight things could have been done better. But we should be judging the actions based on the context of the information at the time. Can we learn from the past and do better in the future? Absolutely. But I'm not going to hold every single Liberal at fault for the decisions of Trudeau.
