"Republicunt": why use terms like this?

[GrandizerII]

I don't use terms like cunts or retards or anything of that matter (I avoid using these terms because of the known offense their usages cause to third party people I have no intention of offending). But as for why resort to insults in general, frustration maybe? To be honest, a lot of views held by some people can be really infuriating (not giving a care for others, the environment, etc.) so using insults against them can be sort of therapeutic.

I get what you're saying, but when someone uses that kind of insult over and over and over it just becomes counterproductive, and I can't imagine being angry makes them a happier person. Is consistent loathing towards a group of people something that really helps? Like, freaking out at someone who is pissing you off is kind of satisfying, but when it's your entire view on the issue, I can only see that making you miserable. For you're specifically seeing the bad and not the good in anyone different from you. If it provides any mental benefit it is short lived, negative, and at the expense the person who you are targeting.

Well, I don't regularly insult, but when I do, it's worth it for me. Some people really are pieces of shit, and some of the views people hold tend to reflect the kind of people they are. People against same sex marriage, for example, tend to be homophobic or, at best, selfish people lacking empathy for people different from themselves. Rarely if ever is the reason just simply about different values. I'm sorry, but it's hard to unconditionally respect people. And yeah, I'm not the type who sees good in everyone. If a person is most of the time nothing but unpleasant, I do not care to see if there is any good in them. They're not worth any good judgement on my part.

Just being honest. I don't like bullshitting much.

EDIT: I still generally have civil discourses with people who hold views that insult me (whether intellectually or morally) but in my mind, I do get pissed off unless I'm in a good mood [not freaked out, btw, just pissed], and in fact, I have relatives who indeed piss me off with some of the views they hold. I still talk to them regardless because not all such people are utterly unpleasant, just people who I wish were better than they currently are.
