Why take special steps now? Because up until now, there has been nothing that I could have come into contact with that had as great a chance of making someone sick and killing them, apart from AIDS, which is why I wore condoms (that and the fact that I don't want to accidentally make a baby). TB is bad as well, but as long as you're reasonably healthy your chances of getting infected and becoming a transmission vector are incredibly low. I learnt this from my father who worked in a TB clinic, but here's some information if you'd like to know more:

I would agree that there's always been fear, particularly around the start. No-one knew what the hell was going on and some of the predicted numbers looked insane. Now we know more, and I make my decisions based on protecting those around me. Others may still be kak scared, but it's not like every time I go to the shops I am going "Omg I might get this virus and kill my gf's parents". Now I am taking every reasonable precaution based on expert advice to protect the people I love and go about my business.
If you want to argue because I am scared of potentially killing someone I care about, then sure, maybe it's fear based, but it's not like every waking moment I spend outside around people (even the people I come across who don't take precautions) has me going "OMG I GOT COVID!" and has me locking myself away. Do I feel scared when I go outside? No. More often I feel shocked when I see people who treat this disease like it doesn't exist.
