Literally not why lol you absolute dreamer
Normally people who back this "I can talk how I like to people cos I'm being honest" are either genuinely autistic and can't read emotions, or they have just had a shitty homelife, parents or upbringing. I suspect you're the second.
When I read a statement like this, I can give you two answers:
1st answer (direct): You are obviously too stupid to understand the difference between being direct and trying to insult people for the sake of insulting or some sick personal satisfaction.
2nd answer (insulting): Whatever, I can just hope your cage bars are made of solid material so you don't get out and your walls are soft so you don't hurt yourself.
It's your choice what kind of conversation you want to have.
You seem to not be introspective enough to tell the difference in your own motivations.
