It is rude. It is also precise and accurate.
From Dictionary.com:
n. (pûrvûrt)
One who practices sexual perversion.
But, once again, you are generally quick to assume what I mean, even when the word doesn't have as well known a meaning as pervert. Why, this time, were you asking me for details? You have never asked me what I mean by 'morality' or 'morals', for example. Yet we have discussed it many times and I have begun to think that you don't use the terms the same way I do, so clarification is needed. But in this case you ask.
When someone changes character so abruptly, it does cause others to wonder why.
Shalom.
P.S. I don't know if you are a pervert or not. You haven't discussed your sexual behavior with me, for which I am profoundly greatful. You have defended perversion. But that does not make you a pervert.
About whom is it accurate?
One would think that a man bold enough to toss the word around, would have the courage and integrity to stand behind it, and tell us who he is talking about.
But I guess that's a lot to ask.
Out of curiosity, can you understand the difference between condemnation of government imprisonment (or worse) of consenting adult homosexuals, and endorsement or defense of their behavior?
I know it's a complex thought, but take a moment and consider it.
