They're just words. If you want to give those words so much power over you, that's your own problem to deal with. What right do you have to demand the rest of society cater to your particular hangups?

When I hear curse words, they elicit exactly the same emotional response as any other word. There's nothing magical or inherently special about them, it's all in your own psychology.

Do you think the same about the n-word?

Yes. To quote Lenny Bruce "'to' is a proposition and 'come' is a verb" (this wasn't eveny about cursing back then, you see)
