"Republicunt": why use terms like this?

[Joods]

I agree. I have no problem with the use of the insults cunt, faggot, gay, retard, slow, blind, stupid, deaf, and so on,

bolding mine.

Of course you don't have a problem with it. You admit those words are insulting so that only confirms that you lack empathy, compassion and the common sense to understand that out of over hundreds of thousands of words in the English language, you choose those as descriptors. How thoughtful and considerate of you. You are also lumping words that are acceptable in with words that aren't. 

and to the people that are hurt by reading these words, maybe the internet is just not the place for you,

Oh sweetheart, the internet has nothing to do with the use of those words. Someone could use those words in a verbal, face to face conversation and they would still be ignorant of the fact that those words do indeed cause harm. And they would still use them in the same derogatory manner as if they were used, let's say, here, in a forum. 

 but when someone is using those terms multiple times a day, they come off like an 8 year old who just learned those swear words and thinks they're being oh so cool by cursing so much.

So you don't have a problem with someone using those words in general and their target audience should just get the hell over it, but if they use them more than once per day, then you have a problem with it?
