i have a full normal happy life full of people and stuff and we just test frequently, mask indoors in public places, and don't hang out if we're sick. it's like 5-10 mins of effort a week. if you don't want to do it you can just say that and 99% of people already agree with you.
I feel for severely ill immunocompromised ppl and recoil at the ridicule they get, but permanent full-on COVID caution is unsustainable if you still can and try to maintain a semblance of a normal life. It's social suicide and a completely nonexistent concept outside the west
