Let's take a vote

While I can concede that name calling is in general not good form, I would like to ask this following question.

Is calling a guy Bastard as bad as calling a girl Bitch?

I personally think the latter is much worse and is misogynistic. However, I do admit that in the past, I have called guys bastard mostly in a joking manner. I don't even honestly think that if I were truly pissed off at someone and called him a "bastard" that it would be a strong enough put down. However, calling someone a Bitch is usually strong enough on its own as a real insult. Therefore, in my mind at least, the two are vastly different and serve different purposes in our everyday lexicon.

Furthermore, the dictionary terms are as follows:

bastard:
A child born out of wedlock.
Something that is of irregular, inferior, or dubious origin.
Slang. A person, especially one who is held to be mean or disagreeable

bitch
A female canine animal, especially a dog.
Offensive.
A woman considered to be spiteful or overbearing. A lewd woman.
A man considered to be weak or contemptible.
Slang. A complaint.
Slang. Something very unpleasant or difficult.

I will also concede that my opinion may be biased due to gender, however I am truly trying to analyze this question objectively.
