Let me try and follow your logic here. You say the vaccine doesn't stop you from catching or spreading the virus, it just stops you from getting as badly sick.

Let me try and follow your logic here. You say the vaccine doesn't stop you from catching or spreading the virus, it just stops you from getting as badly sick. If that's the case then why do you care whether others are vaccinated or not? If it doesn't change the chances of them passing it on to you, and just changes how sick they'll get, then surely it doesn't make any difference to you?
