Look up scare stories in the DM – google the DM's list of things that give you cancer
The DM can sometimes be good if it's just copying things without commenting, I've seen some interesting old photos but much stuff on there is racist, the online version and the facebook site are very racist, there is much that is hateful
I knew some people for several years and got on very well superficially, but when they moved away and I was invited to become Facebook friends oh gosh, so much hate, racism, islamophobia, anti climate change, things have never been bettter, I was horrified. I'd feel very different about them in person nowadays, suppose I had introduced them to someone they were hateful about
I've also been surprised how some seemingly sensible people have come out as covid conspiracy believers, anti-mask, anti-vax, anti lockdown, covid is just a bad dose of flu and children don't get it, it's not deadly, thank heavens I'll not run into them, I don't think I could cope with risking the subject coming up, I'd always thought they could weigh up the evidence and make sensible decisions.
I judge people who kill and abuse and do not think they have done wrong, I judge neonazis and those who knowingly and by choice do wrong, you can't be too tolerant. Obviously, you can be tolerant of things that don't hurt anyone, people do differently and it's not a criticism of those who have different opinions. But so many people say well we did so and so and it never did me any harm, but if you hurt people in any way that is wrong, you learn better and do better, some say you don't need to use proper restraints for children in cars, they never were strapped in, but we know better now and protect the vulnerable
