I use tinder to say rude and hurtful things to girls I've matched with

The need to feel superior to others is a major cause for people who put others down. If you need attention from people, find more positive outlets to do it without making it at others' expense.
I'm not at fault here.
It's your choice to be this way but you can change if you stop now.
