If making friends is one of their priorities, they can find ways to make friends even with a tellblocker on. Other people are not owed an ability to send private messages to them.
You are not owed the ability to give someone compliments, and they do not owe it to you to receive your compliments.Like, if you ran into me, I might message you to talk about your excellent glamour, or your name, or any number of things, and I would never send toxic messages like the example you outlined above.
"Not all men..."I am not unique, in fact people like myself are the vast majority.
Sometimes it only takes 1.Compare the number of good or neutral interactions you have with other people to the number of bad interactions, and you will see they are outnumbered, probably 1000:1, or ever more.
