If I feel under the weather and I must go out, I’ll wear a mask. Otherwise, no. Society at large has accepted the less dangerous variants as a fact of life.
During the pandemic I wore them everywhere. A large section of society showed they couldn’t be fucking bothered so here we are.
My take is because people are largely selfish and ignorant beyond their day to day life. Their favorite politicians/personalities told them masks infringe upon their freedoms and they bought it hook, line, and sinker.
Once someone is convinced they’re right, no amount of evidence or information will sway them. Especially now since they have ready access to any echo chamber of their choice and it’s super easy to filter out dissenting information.
