So what's wrong with saying "Raqa"? Is it a Hebrew swear word?
Not really. It appears to be the Greek spelling of an Aramaic word that means "empty-headed."
It's natural enough to have bad feelings toward other people at times. But actually to call people such names is unkind. Normally, you don't do it to their face. You do it behind their back when you're taking to others. Sometimes you do it with a humorous twist. That's even worse. The more humorous it is, the deeper it cuts, because clever insults are the ones that stick.
You've gotten used to doing this. There are a lot of bad examples around.
It's Lent.
Jesus is quite clear about insulting others (take another look at the Gospel text). You should take a good look at the name-calling you have done in your life, and clean it out of your system.
