There’s many things people do that they shouldn’t and the answer usually boils down to one 2 or all 3 of the following 3 things.
1. They dont know its a problem.
2. They know its wrong but dont understand the implications or havent yet internalized the seriousness of the issue.
3. They know its wrong and they know how wrong it is but they dont care enough to change. (Usually because other people do it too so its easy to feel that you aren’t that bad. )
