I'm insecure about my appearance and this has led me to creeping on women online.
Can you tell me more about why you're creeping on women online?
I like to send them DM's and say rude things.
Feeling insecure about yourself is not an excuse for acting inappropriately towards women online. You should never do that sort of thing because it makes people feel threatened and uncomfortable.
Whatever I like to do it. It doesn't mean that I'll ever meet with these women in real life.
The internet is real life. What you say to these women affect how they feel. Their feelings are real so what you're doing is still inappropriate.
