Do these things happen to you in real life (outside of family but work or friends let’s say?) or just Facebook? Facebook is a huge source of drama, especially when people start political discussions. Who are these people that you befriend on Facebook? Do you know them in real life?

To answer your question though, yes in many ways we do teach people (not strangers though)how to treat us.

In particular if for example someone is being abusive towards you, but you allow that or try to appease them and continue accept their abuse, then you do teach them (not always conciously of course) that abuse is fine with you. Abuse always escalates in these circumstances. If abuser would try this with someone else, someone who wouldnt tolerate it, they’d be dumped like hot potatoe after try #1. Hence abusers kind of prey on people who will tolerate abuse

But that’s in real life not on Facebook. Not sure about this FB dynamic
