Your words don’t exist in a vacuum.

Oh yeah? Are you going to call him the n word?

so instead of using terrible words that accurately describe him, you want to use words that hurt other people way more than they hurt the person adresssed and that criticise a characteristic that is not negative?

is nazi not bad enough?

Imaginary scenario:

You’re at war, the enemies are closing in on the edges of your base. Everyone is using modern weapons, and each attack is precise and deliberate. You, watching your fellow soldiers fall in tandem with scores of the enemy, have decided that enough is enough. You’re gonna pull out the big guns and end this already!

So, you roll a cannon to the center of your base, and start firing chain balls while rotating a few degrees between shots. Sure, each volley from you is likely to do some crazy damage to the enemy. But you’re primarily ripping through your own forces and defenses with no concern for whoever stands between you and your enemy. If your fellow soldiers didn’t know any better, they’d think that your entire goal was to attack your own team.

Don’t use archaic insults that are guaranteed to hurt your friends. You have no clue if the subject of your attack is even paying attention (he’s not), and they’re going to get far more delight out of how offended your friends are by your words.
