Why do some people have to make nasty comments?

Some people are just assholes.

People here come from the world. The world has nasty people. The ability to remain anonymous makes online interaction their dream come true.

Some people are just unhappy and insecure and it validates them to be shitty to others.
Pity them

people do a lot of that online. theres a lot of hate, and some people will gang up on others. its part of the anonymity and people dont have repercussions for their behaviors and actions.

They have poisonous or poisoned hearts and it just comes out sometimes.

Unfortunately, such is the nature of the internet. 🤷🏽‍♂️

It's our own personal issues being projected.

They're miserable and feel safe behind the anonymity of the internet and use that shield to be an asshole.

Good for them, I guess.
